What's the Least Common Multiple (LCM) of 12 and 66?

Answer

LCM of 12 and 66 is
132

First common multiples: 132, 264, 396, …

132 is divisible by both: 132 ÷ 12 = 11, 132 ÷ 66 = 2 — and 11 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/12 by 11 and of y/66 by 2.

12 = 22 × 3

66 = 2 × 3 × 11
