What's the Least Common Multiple (LCM) of 8, 10 and 24?

Answer

LCM of 8, 10 and 24 is
120

First common multiples: 120, 240, 360, …

120 is divisible by all three: 120 ÷ 8 = 15, 120 ÷ 10 = 12, 120 ÷ 24 = 5 — and 15, 12 and 5 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/8 by 15 and of y/10 by 12 and of z/24 by 5.

8 = 23

10 = 2 × 5

24 = 23 × 3
