When we have to factorize a number which is the product of 2 large primes.....then the divisibility rules do not help much.....we need to have a method to find those two large primes.....watch this video to learn how we can get to the factors in 10 seconds.....too good for students of class VI and above and for competitive exams.....for more videos, keep visiting:

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.

@JMartinez69261
@JMartinez69261 4 года назад
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.
