    What's the Least Common Multiple (LCM) of 121 and 280?

    Answer

    LCM of 121 and 280 is
    33,880

    First common multiples: 33,880; 67,760; 101,640; …

    33,880 is divisible by both: 33,880 ÷ 121 = 280; 33,880 ÷ 280 = 121 — and 280 and 121 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/121 by 280 and of y/280 by 121.

    121 and 280 are coprime (GCF = 1), so their LCM is simply the product: 121 × 280 = 33,880.

    121 = 112

    280 = 23 × 5 × 7

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

    LCM = 23 × 5 × 7 × 112 = 33,880
