Question

Find the HCF of 16, 28.

Answer 1

HCF is the product of the common factors of the given numbers.

First, we need to find the prime factors of the given numbers:

$16=2\times 2\times 2\times 2=2^4$

$28=2\times 2\times 7=2^2\times 7$

So, $H.C.F.=2^2=4$

Hence, HCF if the given numbers is $4.$
