    What's the Least Common Multiple (LCM) of 121 and 169?

    Answer

    LCM of 121 and 169 is
    20,449

    First common multiples: 20,449; 40,898; 61,347; …

    20,449 is divisible by both: 20,449 ÷ 121 = 169; 20,449 ÷ 169 = 121 — and 169 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 169 and of y/169 by 121.

    121 and 169 are coprime (GCF = 1), so their LCM is simply the product: 121 × 169 = 20,449.

    121 = 112

    169 = 132

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

    LCM = 112 × 132 = 20,449
