Question

If the LCM of two numbers is equal to their product then their HCF is

• A. 4
• B. 1
• C. -3
• D. 2

Answer 1

The correct option is B 1

Let the two numbers are x and y

Then product of them =xy= LCM of number

We know that Product of two numbers = Product of their H.C.F. and L.C.M

Then HCF=$\frac{xy}{xy}=1$
