    What's the Least Common Multiple (LCM) of 7, 8 and 14?

    Answer

    LCM of 7, 8 and 14 is
    56

    First common multiples: 56, 112, 168, …

    56 is divisible by all three: 56 ÷ 7 = 8, 56 ÷ 8 = 7, 56 ÷ 14 = 4 — and 8, 7 and 4 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/7 by 8 and of y/8 by 7 and of z/14 by 4.

    7 — prime

    8 = 23

    14 = 2 × 7

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

    LCM = 23 × 7 = 56
