    What's the Least Common Multiple (LCM) of 63 and 81?

    Answer

    LCM of 63 and 81 is
    567

    First common multiples: 567; 1,134; 1,701; …

    567 is divisible by both: 567 ÷ 63 = 9, 567 ÷ 81 = 7 — and 9 and 7 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/63 by 9 and of y/81 by 7.

    63 = 32 × 7

    81 = 34

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

    LCM = 34 × 7 = 567
