Java Program to Find LCM of Two Numbers

In this video, we will Find the LCM of 2 numbers. LCM (Least Common Multiple) of two numbers is the lowest number that can be divided by both numbers.

A simple solution to find LCM is to calculate all prime factors of both numbers, also find the union of all factors present in both numbers. Eventually, return the product of elements in union. 

We use two different approaches to find the LCM of 2 numbers
1. Using factors of two numbers with a while loop.
2. Using HCF (Highest Common Factor)

For example:
LCM of 3 and 27 is 27.
LCM of 25 and 65 is 325.
