If Two Positive Integers M and N Are Expressible in the Form M = Pq3 and N = P3q2, Where P, Q Are Prime Numbers, Then Hcf (M, N) = - Mathematics

MCQ

If two positive integers m and n are expressible in the form m = pq3 and n = p3q2, where pq are prime numbers, then HCF (mn) = 

Options

  • pq

  • pq2

  • p3q2

  • p2q2

Solution

Two positive integers are expressed as follows:

`m= pq^3`

`n = p^3,q^2`

p and q are prime numbers.

Then, taking the smallest powers of and q in the values for m and n we get

HCF `(m,n)=pq^2`

Hence the correct choice is (b).
