    What's the Least Common Multiple (LCM) of 18 and 22?

    Answer

    LCM of 18 and 22 is
    198

    First common multiples: 198, 396, 594, …

    198 is divisible by both: 198 ÷ 18 = 11, 198 ÷ 22 = 9 — and 11 and 9 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/18 by 11 and of y/22 by 9.

    18 = 2 × 32

    22 = 2 × 11

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

    LCM = 2 × 32 × 11 = 198
