What's the Least Common Multiple (LCM) of 16, 24 and 40?

Answer

LCM of 16, 24 and 40 is
240

First common multiples: 240, 480, 720, …

240 is divisible by all three: 240 ÷ 16 = 15, 240 ÷ 24 = 10, 240 ÷ 40 = 6 — and 15, 10 and 6 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/16 by 15 and of y/24 by 10 and of z/40 by 6.

16 = 24

24 = 23 × 3

40 = 23 × 5
