Alternative rules for 4, 8 and 16: 4: If after division by 2, the number is still even, the number is divisible by 4. 8: If after division by 2 twice, the number is still even, the number is divisible by 8. 16: If after division by 2 thrice, the number is still even, the number is divisible by 16.

[@Henrique.tRo_Real]

32: If after division by 2 four times, the number is still even, the number is divisible by 32. 64: If after division by 2 five times, the number is still even, the number is divisible by 64. 128: If after division by 2 six times, the number is still even, the number is divisible by 128. And it goes on forever.

[@NSUHardsign]

If this shows an example, in those tables- I'll give you an example, the table of 8 right? Must skip numbers that are multiplied by odds in the table of 4

[@matiaspereira9382]

Here I have alternative rules for 4, 8 and 16: 4: The 10s digit is even and the last digit is 0, 4 or 8, or the 10s digit is even and the last digit is 2 or 6 8: The 100s digit is even and the last 2 digits are 00 or a multiple of 8, or the 100s digit is odd and the last 2 digits are the result of multiplying 4 by an odd number 16: The 1,000s digit is even and the last 3 digits are 000 or a multiple of 16, or the 1,000s digit is odd and the last 2 digits are the result of multiplying 8 by an odd number

[@marcusscience23]

Rather than list out all the numbers one by one, here are generalised rules, the positive integers split into 4 categories: Powers of 2 (2^n): check last n digits Powers of 5 (5^n): same as above Relatively prime with 10 (p): multiply last digit by 10^[-1] mod p (modular multiplicative inverse) and add remaining truncated digits (repeat as necessary) Other composites: apply rules of greatest factors belonging in each of the above categories (if present)

For divisibilty rule of 7, you can also take out the last digit, multiply the remaining by 3 and then add the digit you removed to the result.

[@LaGGSBD]

No, i dont mean that. It should be this gonna edit it for that: 315 ----> 31x3=93 ----> 93+5=98 98 ----> 9x3=27 ----> 27+8=35 which is divisible by 7

Easier way to determine whether a number is a multiple of 4. If the tens digit is even, it’s only a multiple of 4 if the ones digit is 0, 4, or 8. If the tens digit is odd, it’s only a multiple of 4 if the ones digit is 2 or 6.

Tip for divisibility of 11 only can be used in a 3 digit number The middle digit should be the SUM of first and last digit For example 253 2+3=5, 253 is divisibile by 11

[@TheCounter46]

10 factorial 1 - 3628800 is a number, so it is divisible by 1 2 - 3628800 362880 - 0 -> 362880 -> 36288 - 0x2 -> 36288 - 0 -> 36288 -> 3628 - 8x2 -> 3628 - 16 -> 3612 -> 361 - 2x2 -> 361 - 4 -> 357 -> 35 - 7x2 -> 35 - 14 -> 21. 21 is divisible by 7 so 3628800 is divisible by 7 8 - 907200 / 2 = 453600, so 3628800 is divisible by 8 9 - going back to 3, shows that the final number is 9, so 3628800 is divisible by 9 10 - 3628800

I would adjust the rules for the powers of 2 (only 4, 8, and 16 were shown in this video) so they check that power's place digit for even/odd, then do the check for the next power of 2 down with the lower digits. If odd, add that lower power of 2 to the lower digits before checking. When we reach 4, even should have 0, 4, or 8 in the ones place and odd should have 2 or 6. This avoids any long division and is extendable to all powers of 2. Is 10,848 divisible by 16? 0 is even so, is 848 divisible by 8? 8 is even so, is 48 divisible by 4? 4 is even so, we're left with 8 and yes, 10,848 is divisible by 16. Is 10,928 divisible by 16? 0 is even so, is 928 divisible by 8? 9 is odd so, is 28 + 4 = 32 divisible by 4? 3 is odd so, we're left with 2 and yes, 10,928 is divisible by 16. Is 125,518,848 divisible by 512 (2^9)? 1 is odd so, is 25,518,848 + 256 = 25,519,104 divisible by 256? 2 is even so, is 5,519,104 divisible by 128? 5 is odd so, is 519,104 + 64 = 519,168 divisible by 64? 5 is odd so, is 19,168 + 32 = 19,200 divisible by 32? 1 is odd so, is 9,200 + 16 = 9,216 divisible by 16? 9 is odd so, is 216 + 8 = 232 divisible by 8? 2 is even so, is 32 divisible by 4? 3 is odd so, we're left with 2 and yes, 25,518,848 is divisible by 512!

For 7, 11, 13 make uae of the fact that 7*11*13=1001 to never have to deal with numbers above 1000. Example: 2639. Divide into groups of 3 and do the alternating sum, just like for 11. In this case you have to test 2-639=-637. Now you can check for divisibility by 7, 11 and 13 of this number. It's obviously divisible by 7, as 637=91*7 and 91 is divisible by 13, thus your original number is divisible by 7 and 13.

OK.

[@ashtonplays2613]

I can make 24 - 26 for you. 24 - repeat unusual 3 and 8 25 - last 2 numbers are divisible by 25 26 - repeat unusual 2 and 13

[@ashtonplays2613]

I have more: 27 - get last digit, multiply by 8, subtract the remaining, result must equal to a multiple of 27 28 - repeat unusual 4 and 7 30 - repeat unusual 3 and 10 or 2 and 15 33 - repeat unusual 3 and 11 34 - repeat unusual 2 and 17 36 - repeat unusual 4 and 9 37 - get last digit, multiply by 11, subtract the remaining, result must equal to a multiple of 37 38 - repeat unusual 2 and 19 40 - repeat unusual 4 and 10 or 5 and 8 42 - repeat unusual 2 and 21 44 - repeat unusual 4 and 11 45 - repeat unusual 5 and 9 46 - repeat unusual 2 and 23 47 - take last digit, multiply by 14, subtract the remaining, result must equal to a multiple of 47 50 - repeat unusual 2 and 25

Nice video, very tricky

[@sevturner2685]

0:46 or you can multiply 1's digit by 5 then add that to the remaining example: 123 is 12+(3x5)

[@sevturner2685]

or just do the same as 17

[@esthervolley2343]

Awesome video... Smart, clear & time saving... Except for the mistake of divisibility rule 17.. ( it must be subtracted)

[@beastgamerutkarsh5804]

You told divisibility of 17 second step add to remaining you subtract bro ??

Additional rule for 4: If a even numbers half is even then it’s divisible by 4 Example 1: Half of 24 is 12 and 12 is even so 24 is divisible by 4 Example 2: Half of 30 is 15 and 15 is odd so 30 is not divisible by 4

[@itzarjun4]

In the divisibility rule of 17th, you have mentioned that "Multiply the last digit by 5, Add the remaining digits, the result must be divisible by 7, But in the example you subtracted. Why? 🤔

Since 11,060.5 is a multiple of 22 but the closest INTEGER MULTIPLE are 11,044 and 11,066 and thus, 11,060.5 isn't a integer multiple of 22.

[@darshraatparsadhraj5583]

1:08 But what if the number itself is only 3 digits?

[@mr.duckie._.]

divisible by 8 if the number is divisible by 8

[@ranjeetkumar-dl6tb]

I just wanted to know that in the divisibility test of 20 it must end with 20,40,60,80 and 00 or it will end with all multiples of 20?

[@user-xl5vc1me6t]

The video is very fast i cant see properly

[@prashantchaudhary2193]

Brother in 11 divisibility rule how you take 8 as a odd number and 3 as a even number??

[@alaricwitoyo2713]

He doesn’t take the odd and even digits, but the odd and even NUMBERED digits. So, in 23657, 2, 6, and 7 are in the 1st, 3rd, and 5th places (odd) while 3 and 5 are in the 2nd and 4th places (even).

2,157,683 Isn’t Just Only Divisible By 11! (2 + 5 + 6 + 3) = 16 - (1 + 7 + 8) = 16 ______________________ 0 (11 Goes Into 2,157,683... 196,153 Times! And 196,153 Is Divisible By 53 Itself, By Going In 3,701 Times Those Are One Of The Bigger Examples Of Using 11’s Divisibility Rule...

[@locomotivetrainstation6053]

Umm

[@bobczech7774]

another way of saying something is divisible by 8 So every 25 multiples is 200 If the first 3 digits are in one of the 25 multiples + 8x(any number that is dividable by 25) So 272 is 8x(25+9)

[@jackm8878]

You don't need to do long division for rule 8. Just do 4.

[@Venni-teju]

Thank you very much for these divisibility rules

[@mateuszszulecki5206]

What is the font used?

[@studycornerdeepa9877]

Nice and to the point..... But one mistake in rule for 17.. We have to multiple last digit by 5 and the ans has to be substracted from remaining digits.... result must be multiple of 17...

[@varenyaarya7228]

divisibility rule for 17 is incorrect. in the rule, it's mentioned to "add" the multiplication with the rest of the number, however, in the example the multiplication was "subtracted" from the remaining number. pls rectify!

[@Calmenergybalance]

Great video, very useful

The test of divisibility of 17 has been subtracted. It must be added according to test of divisibility. Please recover your mistake.

12,580 is not divide by 10. 10, 20. Not number 12,580! It's divide by 0,01. (12 580 divide by 10)
