What's the Least Common Multiple (LCM) of 13 and 6?

Answer

LCM of 13 and 6 is
78

First common multiples: 78, 156, 234, …

78 is divisible by both: 78 ÷ 13 = 6, 78 ÷ 6 = 13 — and 6 and 13 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/13 by 6 and of y/6 by 13.

13 and 6 are coprime (GCF = 1), so their LCM is simply the product: 13 × 6 = 78.
