Question

In Q.No. 7, HCF (a, b) is

 

Options

• pq

•  p³q³

• p³q²

• p²q²

Answer 1

Two positive integers are expressed as follows:

`a= pq^2`

`b= p^3q`

p and q are prime numbers.

Then, taking the smallest powers of p and q in the values for a and b we get

HCF `(a,b) = pq`

Hence the correct choice is (a).
