What is Least Common Multiple?

The least common multiple, abbreviated to LCM, is the lowest or smallest multiple a set of numbers have in common. To understand the concept of LCM, you’ll need to understand the meaning of multiples.

Multiples are the products you get when a number is multiplied by another number. Hence if you’re given three numbers and asked to find their lowest common multiple, you’ll need to list the multiples of each number, identify the multiples that all three numbers have in common, and choose the multiple with the lowest number.

You can find the least common multiple of a group of numbers using different methods. The quickest way to do it is using the prime factorization method. When using this method, you’ll need to find the prime factor of the group of numbers and identify their least common multiple.

Another simple way to find LCM is the listing method explained above. The third way to find LCM is through the division method. In this method, you’ll need to divide the group of numbers by a common divisor until it can no longer divide the remainder. Then multiply the remainders and divisors to get the least common multiple.
