    What's the Least Common Multiple (LCM) of 81 and 99?

    Answer

    LCM of 81 and 99 is
    891

    First common multiples: 891; 1,782; 2,673; …

    891 is divisible by both: 891 ÷ 81 = 11, 891 ÷ 99 = 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/81 by 11 and of y/99 by 9.

    81 = 34

    99 = 32 × 11

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

    LCM = 34 × 11 = 891
