One of the method to approach such problem is assuming prime numbers nearest to the square root of that said number, because in that case the pair of numbers will be least distant to one another. While testing, the further one of the factors move away from square root of number, the further the other factor will move, in opposite direction.

Thank you sir you always tell best tricks and shortcuts, but I have a doubt that how we will check whether a number (big number) is itself a prime number or is product of prime numbers?

Fantabulous sir! I was confused of such a large number in factorisation method but u really explained those doubts properly with a easy method... Thank you sir.

Thankyou so much sir! I was struggling with prime numbers You made it really easy 🙏

Thank you very much. Quite a bit of trial and error but facinating.

Thankyou sir. It was very helpful!

Hi! Great method! I was wondering about specifically 289 and its factors. Is this one that you have to memorize as 17*17? For numbers ending in 9, are you ever needed to check __7 * __7? Thanks.

Awesome explanation

Thank you so much sir it's clear my doubt about prime factorise

You should include skills required for each video, under the description. Like in this video - Vedic multiplication, divisibility rule for first few primes, primes under 100, squares upto 25 and so on.

Awesome!

excellent sir ....im grateful

thank you, it really helped me

Wat if the factors are more than 4

Awsome Explaination!

what if the number has more than two prime factors?

Thanks sir ❤️❤️

Sir please do the prime factorization for cube number like 79570 if it is a cube or not

@JMartinez69261

4 жыл бұрын

It ends in 0, so we have a ten. The digits do not add to a multiple of 3. Since 1001 is 7*11*13 we can quickly look at the next three. 79570 - 70070 is 9500. 95 is not divisible by 7. Nor 11, nor 13. Next up is 17. 7957-17 = 7940. 794-34 = 760. Not 17. His method has us look at that last 7. And has us looking at factors that can multiple to 7: 3x9 or 1x7. I didn't want to listen to all 13 minutes of the video. I used Google. If you check all the primes (yeah, ending in 1,3,7, or 9 includes all of them) upto the square root of 7957 (89) you will discover 73. 79570 = 2 x 3 x 73 x 109.

Sir.. Please check the number 617

What is the factor of 277 plz

@JMartinez69261

4 жыл бұрын

Did you try 2,3 and 5? How about 7? Remove all the 7 - replace with 0s. Is 200 divisible by 7? Now onto 11. I subtract off the 77 and get 200. Nope. Now onto 13. This is tricky. I add 13 to get 290. Since 290 is not divisible by 13 that means 277 is not. What is the square root of 277 anyway? About 17, so we are almost done. 277 - 17 is 260. Which is not divisible by 17. So, 277 is prime.

In 2 why both of them ending with 9 is not a possibility?
