Question:
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
$x=\frac{12960}{18}$
= 720
Hence, their LCM is 720.
