LCM stands for Least Common Multiple or Lowest Common Multiple. It is the smallest number which is the common multiple of two or more than two numbers given numbers. Least Common Multiple calculator is an easy tool which can be used to immediately find the LCM for any two or more numbers.

Example 1: Find the LCM of the numbers 18, 24 and 36.


First write the prime factorization of all the three numbers.

Then the LCM is the product of the factors which occur at least once in the three numbers!

Prime factorization of 18 =    2 * 2 * 3
Prime factorization of 24 =  2* 2 * 2 * 3
Prime factorization of 36 = 2 * 2 * 3 * 3

LCM of these numbers = 2 * 2 * 2* 3 * 3



Example 2: Find the LCM of the numbers 24, 50 and 88.

Following the same above method, we first take the prime factorization of the given numbers.

 Prime factorization of 24 = 2*2*2*3
 
Prime factorization of 50 = 2*5*5
 Prime factorization of 88 = 2*2*2*11


LCM of these numbers = 2*2*2*3*5*5*11= 6600
