What's the Least Common Multiple (LCM) of 40 and 300?

Answer

LCM of 40 and 300 is
600

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

600 is divisible by both: 600 ÷ 40 = 15, 600 ÷ 300 = 2 — and 15 and 2 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/300 by 2.

40 = 23 × 5

300 = 22 × 3 × 52
