    What's the Least Common Multiple (LCM) of 63 and 77?

    Answer

    LCM of 63 and 77 is
    693

    First common multiples: 693; 1,386; 2,079; …

    693 is divisible by both: 693 ÷ 63 = 11, 693 ÷ 77 = 9 — and 11 and 9 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/63 by 11 and of y/77 by 9.

    63 = 32 × 7

    77 = 7 × 11

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

    LCM = 32 × 7 × 11 = 693
