Prime Number or Composite Number?? How to know if the number is prime or not?

[@subratkumarsahoo577]

As u check n+1 or n-1, Here seems n-1,n,n+1 consecutive so one must be divisible by 3

[@swapnilkadu639]

Thank you so much mam for wonderful content..

My pleasure 😊

[@sudhangshubhattacharya4991]

Take these integers,35,35+1=36,divisible by 3, but 35 is not a prime,rather than this 6m+1 or 6m-1 is a more substantial approach to the prime numbers

[@randomgaming5971]

you taught us upto a level that we can say that 7099 can be a prime No. . . . But you didn't taught full thing. whi wali baat hai k billi ne sher ko sab sikha dia but darakht par charhna ni sikhaya, ta k agar sher usi ko khane aaye to wo apni jan bacha sakey.

7099 can be a prime number

[@vigneshgk1773]

This method really helpful mam. Thz for sharing this method.

[@skrahmanmathematics7731]

Don't follow this rule Example : according to this rule,the number 713 is a prime number but this number is a composite number . The factor of 713 are 1,23,31,713 so this a composite number

Excuse I wanted to know that how to know that till which number we have to take prime numbers for the prime factorization

[@mkfunandlearnvideos8470]

Can u tell me a little fast I have a exam tomarrow

It's shown in the video till square root of the given number you have to take prime numbers

If a number is not divisible by 3 even after doing+1 and -1 , can we be sure that its not prime number or it can still be prime number ??

[@FastandEasyMaths]

It can be a prime

[@gboldero1]

Yes we can be sure because all prime numbers apart from 2 or 3 can be written in the form 6n+1 or 6n-1 and 6 is divisible by 3 and 2.

[@gboldero1]

​@FastandEasyMaths Actually, apart from 2 and 3 all prime numbers can be written in the form 6n+1 or 6n-1

[@RabiKundingi]

I can't understand

[@progamerz8695]

😢😢i can also not understand

[@samsonthomas4095]

What if both the number divisible by 3, There can we say that is a prime number ? Or still it CAN be a prime number.

[@FastandEasyMaths]

No any number which is divisible by any other except itself or 1 is not a prime number

[@nandkumars.vanamali1336]

No two numbers that have a difference of 2 will BOTH be divisible by 3

Mam can you please make a vedio for me please only composite numbers please 🙏🙏🙏🙏🙏🙏🙏

[@dr.kedargupta5855]

i made notes as you got the concept clear and the answer to DIY is = It can be a prime no.

[@ashu-dnext]

I got a question to find prime number from four options a) 187 b) 221 c) 391 d) 307 I was ur trick and to my surprise, according to ur trick(n-1, n+1 div by 3): it tells all can be a prime number. TRICK FAILS??

[@FastandEasyMaths]

No the truck also says all can be prime numbers, this trick actually helps you to discard numbers which surely are composite

[@suryamouli253]

*_Good Evening ma'am...._* Ma'am firstly thank you so much for this video... *_Do It Yourself...._* Q) 7099 Is a prime number or not...?? A) the rule is : * n+1 or n-1,the result is divisible by 3..if yes,then n can be a prime number.... So, 7099+1=7100 which is not divisible by 3 as he sum of the numbers is 8 and is not divisible by 3.. 7099-1=7098 which is divisible by 3 as the sum of the number is 24 and is divisible by 3.... Hence, 7099 can be a prime number.... *_Thank you Ma'am...._*

Perfect Surya 🥰

[@rangafauji9085]

n + 1 & n-1 if divisible by 6 then it is possible for it to be a prime number, it's not 3 for gods sake

Divisible ka word mujhe thora hindi me smjhayega phr mere ye smjh ajaega?

[@Itzy-ive-g-idle-4ever]

Meaning it can be divided with the number as in it is in the table of the number like 21 is divisible by 3 because it comes in its table as 3 x 7 = 21 Hope this helps

49 is odd and is still composite?

[@FastandEasyMaths]

Yes, it is. Pls watch the video it's mentioned there properly😊

Namaste.... This dont work for the number 91....... 91 is a composite number. 13×7=91. But the method u explained says 91 is a prime number.....

No it doesn't pls see the video fully

But for 49 it is not applicable.... As 48-1 divisible by 3.... But 49 is not prime
