    What's the Least Common Multiple (LCM) of 25, 30 and 45?

    Answer

    LCM of 25, 30 and 45 is
    450

    First common multiples: 450; 900; 1,350; …

    450 is divisible by all three: 450 ÷ 25 = 18, 450 ÷ 30 = 15, 450 ÷ 45 = 10 — and 18, 15 and 10 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/25 by 18 and of y/30 by 15 and of z/45 by 10.

    25 = 52

    30 = 2 × 3 × 5

    45 = 32 × 5

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

    LCM = 2 × 32 × 52 = 450
