What's the Least Common Multiple (LCM) of 12 and 22?

Answer

LCM of 12 and 22 is
132

First common multiples: 132, 264, 396, …

132 is divisible by both: 132 ÷ 12 = 11, 132 ÷ 22 = 6 — and 11 and 6 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/22 by 6.

12 = 22 × 3

22 = 2 × 11

— = power 0: the prime is not a factor of this number; the LCM takes it from the number that has it.

LCM = 22 × 3 × 11 = 132
