    What's the Least Common Multiple (LCM) of 18, 24 and 36?

    Answer

    LCM of 18, 24 and 36 is
    72

    First common multiples: 72, 144, 216, …

    72 is divisible by all three: 72 ÷ 18 = 4, 72 ÷ 24 = 3, 72 ÷ 36 = 2 — and 4, 3 and 2 have no factor but 1 common to all of them, so no smaller number is. As a common denominator: multiply the top and bottom of x/18 by 4 and of y/24 by 3 and of z/36 by 2.

    18 = 2 × 32

    24 = 23 × 3

    36 = 22 × 32
