What's the Least Common Multiple (LCM) of 24 and 56?

Answer

LCM of 24 and 56 is
168

First common multiples: 168, 336, 504, …

168 is divisible by both: 168 ÷ 24 = 7, 168 ÷ 56 = 3 — and 7 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/24 by 7 and of y/56 by 3.

24 = 23 × 3

56 = 23 × 7
