LCM is known as smallest common multiple or Lowest Common Multiple or Least Common Multiple of given numbers.

**Multiple: **A number x is said to be multiple of y when x is exactly divisible by y.

**Ex: **Let’s say x = 15 and y = 3.

Here 15 is exactly divisible by 3. That means 15 is multiple of 3.

A number can be multiple of more than one number. Here 15 is multiple of 3 as well as 5. So 15 is a common multiple of 3 and 5.

3 and 5 has many common multiples. These are 15, 30, 45, 60, 75,…. and so on.

But 15 is smallest of them. So 15 is known as smallest common multiple or Lowest Common Multiple or Least Common Multiple of 3 and 5.

Here one thing is to be noted that LCM is greater than or equal the biggest number of the given numbers.
