The Least Common Multiple (LCM) of a group of numbers is the smallest number that is a multiple of all the numbers. For instance, the LCM of 16 and 20 is 80; 80 is the smallest number that is both a multiple of 16 and a multiple of 20. You can find the LCM of two or more numbers through various methods.
What is least common multiple used for in real life?
LCM Problems may be asking you:
- about an event that is or will be repeating over and over.
- to purchase or get multiple items in order to have enough.
- to figure out when something will happen again at the same time.

Which is the least common multiple of 4 and 5?
In our previous example, the smallest of the common multiples is 20 … so the Least Common Multiple of 4 and 5 is 20. List the multiples of the numbers until we get our first match.
