# Common Multiples

This website provided background information, defines common multiples, and gives examples on how to find common multiples of two numbers. This site could be used in the planning stages of a lesson or as a refresher tool for teachers and/or parents. Multiples are important for teaching multiplication and adding and subtracting fractions with unlike denominators.
