    What's the Least Common Multiple (LCM) of 100 and 105?

    Answer

    LCM of 100 and 105 is
    2,100

    First common multiples: 2,100; 4,200; 6,300; …

    2,100 is divisible by both: 2,100 ÷ 100 = 21; 2,100 ÷ 105 = 20 — and 21 and 20 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/100 by 21 and of y/105 by 20.

    100 = 22 × 52

    105 = 3 × 5 × 7

    222—22

    552552
    7—77

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

    LCM = 22 × 3 × 52 × 7 = 2,100
