What's the Least Common Multiple (LCM) of 40 and 150?

Answer

LCM of 40 and 150 is
600

First common multiples: 600; 1,200; 1,800; …

600 is divisible by both: 600 ÷ 40 = 15, 600 ÷ 150 = 4 — and 15 and 4 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/40 by 15 and of y/150 by 4.

40 = 23 × 5

150 = 2 × 3 × 52

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

LCM = 23 × 3 × 52 = 600
