Finding the smallest common multiple between any two or more numbers is done using the least common multiple (LCM) approach. A number that is a multiple of two or more other numbers is said to be a common multiple. The acronym LCM stands for the least common multiple or factor of any two or more specified integers.
Methods of LCM
There are three key approaches we can use to determine the LCM of two or more numbers. As follows:
- Listing the Multiples
- Prime Factorisation Method
- Division Method
