What's the Least Common Multiple (LCM) of 6 and 39?

Answer

LCM of 6 and 39 is

First common multiples: 78, 156, 234, …

78 is divisible by both: 78 ÷ 6 = 13, 78 ÷ 39 = 2 — and 13 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/6 by 13 and of y/39 by 2.

6 = 2 × 3

39 = 3 × 13

Prime	6	39	Highest power
2	2	—	2
3	3	3	3
13	—	13	13

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

LCM = 2 × 3 × 13 = 78
