What's the Least Common Multiple (LCM) of 72 and 27?

Answer

LCM of 72 and 27 is
216

First common multiples: 216, 432, 648, …

216 is divisible by both: 216 ÷ 72 = 3, 216 ÷ 27 = 8 — and 3 and 8 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/72 by 3 and of y/27 by 8.

72 = 23 × 32

27 = 33
