PRIME or COMPOSITE ? Check in 10 Seconds

Agarawal peoples are legend that's why im using Dr. R.S Agarwal's Elementry Book for competitive exams, it's perfect helping me alot.

Mate .. rs Agarwal books are not good for competitive exam preparation. It's good for academics , you can prefer Pearson,hc,verma,rd Sharma .for exams like NTSE / KVPY

Close perfect square rule:- it's useful upto 4 digit. For bigger no. We confuse and more time. 2- 6n+1, 6n--1 rule has been proven to be false.

[@Corazonlatino1995]

You are wrong!! If I want that I believe to you, make me 1 example!! 🤷‍♂️

[@syedmdabid7191]

Example: 25= 6×4+1, 49= 6×8+1 etc

[@SuperHuman748]

Another Solution :: Take a number say p square it p*p subtract 1 from p*p now divide by 24 if it divided its prime. That's it. Formula is p is prime if [(p*p)-1] ➗ 24=0 then p is a prime number. Only Exception cases where p is 2 & 3.

[@frintasudheeran5131]

For example??

[@koyel4568]

193(193-1)÷24=0 then it is prime. Thanks 😊

@@SuperHuman748 Maybe you wanted to say : *p(p-1)÷24=0* and not {(p*p)-1} ÷24=0 right?

Sir can you make a video for more larger number becz it is in our 10th ncert syllabus sir if you do it it will be very kind of yours

[@Corazonlatino1995]

For example the last number 627 is not only divisible by 3, but by 11 and 19 too. So the prime factor of 627 are 3×11×19 and therefore his submultiply are: 1,3,11,19,33,57,209 & 627. 👍💪🤙🤦‍♂️🇪🇺

[@BNMohapatra1964]

@Sawan Challani , 319 is in the form '6n+-1' i.e. 319=6*53+1, it means it may be a prime number ⁉️ 319

Thanks for making this video. My daughter's homework became easier. But this method is effective as long as step 2 is a small number. When i tried tjis method on 677, i had to find a number square above 677. Kids in grade 6 need a calculator for this, which is prohibited. Lets hope my daughter doesnt get a large number like 677 on a test.
