    What's the Least Common Multiple (LCM) of 20, 25 and 35?

    Answer

    LCM of 20, 25 and 35 is
    700

    First common multiples: 700; 1,400; 2,100; …

    700 is divisible by all three: 700 ÷ 20 = 35, 700 ÷ 25 = 28, 700 ÷ 35 = 20 — and 35, 28 and 20 have no factor but 1 common to all of them, so no smaller number is. As a common denominator: multiply the top and bottom of x/20 by 35 and of y/25 by 28 and of z/35 by 20.

    20 = 22 × 5

    25 = 52

    35 = 5 × 7

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

    LCM = 22 × 52 × 7 = 700
