Question

how to take out hcf in prime factorisation method

Answer 1

First of all, take out prime factors of those given no. Then multiply common factors. Hope I helped u... Plz mark as the BRAINLIEST answer if helpful...

Answer 2

We first have to prime factorize both the numbers. E.g. 50 and 25

50 = 2 * 5 * 5 ,        25 = 5 * 5

Next we take the common factors in both of them...There are two fives(5,5) so we have to multiply them. H.C.F = 5 * 5 = 25.

Thus the H.C.F of 25 and 50 is 25.
