The HCF of two expressions p and q is 1. What is the reciprocal of their LCM

• LCM HCF

The HCF of two expressions p and q is 1. What is the reciprocal of their LCM?

1. p + q
2. p - q
3. pq
4. (pq)^-1

Answer

The product of two polynomials is equal to the product of their HCF and LCM.

HCF × LCM = pq

Given, HCF = 1

So, LCM = pq

1/LCM = (pq)^-1

The correct option is D.
