    What's the Least Common Multiple (LCM) of 84 and 108?

    Answer

    LCM of 84 and 108 is
    756

    First common multiples: 756; 1,512; 2,268; …

    756 is divisible by both: 756 ÷ 84 = 9, 756 ÷ 108 = 7 — and 9 and 7 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/84 by 9 and of y/108 by 7.

    84 = 22 × 3 × 7

    108 = 22 × 33

    — = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.

    LCM = 22 × 33 × 7 = 756
