What is the Least Common Multiple (LCM)?
The Least Common Multiple (LCM) of a set of two or more integers is the smallest positive integer that is a multiple of all the numbers in the set. For example, the LCM of 4 and 6 is 12, because 12 is the smallest number that is a multiple of both 4 (4x3=12) and 6 (6x2=12). The LCM is often used to find a common denominator when adding or subtracting fractions.
