Concept:



How To Use the Concept:

    To find the Least Common Multiple (LCM) of two numbers, find the smallest number that both numbers will divide into evenly.

    Example: Find the LCM of 3 and 4.
    Multiples of 3: 3, 6, 9, 12, 15, 18
    Multiples of 4: 4, 8, 12, 16, 20
    The smallest number that 3 and 4 will divide into evenly is 12.
