Question

Find the hcf of 120 and 150 answer

Answer 1

30. there is a common. no. 2,3and5.
by multiplying this. we can get 30.

Answer 2

First we need to find prime factorization of 120 and 150

We get

120=2*2*2*3*5

150=2*3*5*5

To find gcf we just need to collect only common factors in both.

we see that only common factors are 2*3*5.

Hence hcf will be 2*3*5 or 30.
