If HCF of p and q is x and q = xy, then the LCM of p and q is = ?

A. pq

B. qy

C. xy

D. py

Answer: Option D

Solution(By Examveda Team)

$$\eqalign{ & {\text{Product of numbers}} \cr & {\text{ = HCF}} \times {\text{LCM}} \cr & \Rightarrow pq = x \times {\text{LCM}} \cr & \Rightarrow {\text{LCM}} = \frac{{pq}}{x} \cr & = \frac{{p\left( {xy} \right)}}{x} = py \cr} $$
