    What's the Least Common Multiple (LCM) of 81 and 121?

    Answer

    LCM of 81 and 121 is
    9,801

    First common multiples: 9,801; 19,602; 29,403; …

    9,801 is divisible by both: 9,801 ÷ 81 = 121; 9,801 ÷ 121 = 81 — and 121 and 81 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/81 by 121 and of y/121 by 81.

    81 and 121 are coprime (GCF = 1), so their LCM is simply the product: 81 × 121 = 9,801.

    81 = 34

    121 = 112

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

    LCM = 34 × 112 = 9,801
