    What's the Least Common Multiple (LCM) of 80 and 155?

    Answer

    LCM of 80 and 155 is
    2,480

    First common multiples: 2,480; 4,960; 7,440; …

    2,480 is divisible by both: 2,480 ÷ 80 = 31; 2,480 ÷ 155 = 16 — and 31 and 16 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/80 by 31 and of y/155 by 16.

    80 = 24 × 5

    155 = 5 × 31

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

    LCM = 24 × 5 × 31 = 2,480
