# The Hcf of Two Numbers is 18 and Their Product is 12960. Find Their Lcm. - Mathematics

The HCF of two numbers is 18 and their product is 12960. Find their LCM.

#### Solution

HCF of two numbers = 18
Product of two numbers = 12960
Let their LCM be x.
Using the formula, product of two numbers = HCF × LCM
we conclude that
12960 = 18 × x
x = 12960 / 18
= 720
Hence, their LCM is 720.
