    What's the Least Common Multiple (LCM) of 55 and 80?

    Answer

    LCM of 55 and 80 is
    880

    First common multiples: 880; 1,760; 2,640; …

    880 is divisible by both: 880 ÷ 55 = 16, 880 ÷ 80 = 11 — and 16 and 11 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/55 by 16 and of y/80 by 11.

    55 = 5 × 11

    80 = 24 × 5

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

    LCM = 24 × 5 × 11 = 880
