What's the Least Common Multiple (LCM) of 12 and 13?

Answer

LCM of 12 and 13 is
156

First common multiples: 156, 312, 468, …

156 is divisible by both: 156 ÷ 12 = 13, 156 ÷ 13 = 12 — and 13 and 12 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/12 by 13 and of y/13 by 12.

12 and 13 are coprime (GCF = 1), so their LCM is simply the product: 12 × 13 = 156.

12 = 22 × 3

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

LCM = 22 × 3 × 13 = 156
