Question

The hcf of two numbers is 12 and thier lcm is 864.If one of the number is 64 then find out the other number

Answer 1

Given that the HCF of two numbers is 12 and their LCM is 864 and one of the number is 64.

Assume that the other number is x.

So we know that

First number×Second number = HCF×LCM

64×x = 12×864

⇒ x = (12×864)/64

⇒ x = (3×864)/16

⇒ x = 3×54

⇒ x = 162

Hence the other number is 162
