Question

the hcf of two number is 4 and their Lcm is 128. if one of the two numbers is 16 ,find the other number

Answer 1

Let the other number be x.

Given that HCF of two numbers is 4 and LCM is 128.

We know that product of two numbers = HCF * LCM

= > 16 * x = 4 * 128

= > x = (4 * 128)/16

= > x = 32.

Therefore, the other number is 32.

Hope this helps!
