How do I Find the LCM of a Number?

In arithmetic concepts, the least, lowest or smallest common multiple is the smallest positive integer that is divisible by both of the given numbers. LCM is also recognised as the Least Common Divisor or LCD.

The LCM of two integers a and b is indicated as LCM(a, b) or as [a, b] in some older textbooks.

It is used to mind the lowest common multiple between two or more numbers. A common multiple is a multiple that is mutual in a given set of numbers.

There are three fundamental techniques by which you can discover the LCM of two or more numbers. The methods are –

  1. Listing the Multiples Method 
  2. Prime Factorisation Method
  3. Division Method

How to Find LCM Without Using a Calculator?

It is easy to find out LCM without using a calculator by Listing the multiples Method. Follow the steps given below to calculate.

  1. Let's refer to them as A, B, C, D & E to evaluate the LCM of the five numbers.
  2. List the first few multiples of A, B, C, D and E.
  3. Find out the common multiples from the multiples of all five numbers and mark them.
  4. Choose the smallest common multiple. 
  5. Finally, the lowest common multiple is the Least Common Multiple or LCM of the five numbers.

Solved Example Determining LCM of 5 numbers


Find out the LCM of five numbers are 3,6,7,14 and 21.


Firstly, let's list the first few multiples of the five numbers —

Multiples of 3 are 3, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42…

Multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48, and 54…

Multiples of 7 are 7, 14, 21, 28, 35, 42, 56, 63…

The multiples of 14 are 14, 28, 42, 56, 70, and 84…

The multiples of 21 are 21, 42, and 63.

Now compare the multiple for the 5 numbers and find out the least common multiple.

As we can see, the smallest common number that is on all of the lists is 42.

So LCM of 3,6,7,14 and 21 is 42.
