    What's the Least Common Multiple (LCM) of 16, 20 and 32?

    Answer

    LCM of 16, 20 and 32 is
    160

    First common multiples: 160, 320, 480, …

    160 is divisible by all three: 160 ÷ 16 = 10, 160 ÷ 20 = 8, 160 ÷ 32 = 5 — and 10, 8 and 5 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/16 by 10 and of y/20 by 8 and of z/32 by 5.

    16 = 24

    20 = 22 × 5

    32 = 25

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

    LCM = 25 × 5 = 160
