    What's the Least Common Multiple (LCM) of 54 and 81?

    Answer

    LCM of 54 and 81 is
    162

    First common multiples: 162, 324, 486, …

    162 is divisible by both: 162 ÷ 54 = 3, 162 ÷ 81 = 2 — and 3 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/54 by 3 and of y/81 by 2.

    54 = 2 × 33

    81 = 34

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

    LCM = 2 × 34 = 162
