What's the Least Common Multiple (LCM) of 2, 8 and 13?

Answer

LCM of 2, 8 and 13 is

104

First common multiples: 104, 208, 312, …

104 is divisible by all three: 104 ÷ 2 = 52, 104 ÷ 8 = 13, 104 ÷ 13 = 8 — and 52, 13 and 8 have no factor but 1 common to all of them, so no smaller number is. As a common denominator: multiply the top and bottom of x/2 by 52 and of y/8 by 13 and of z/13 by 8.

2 — prime

8 = 2³

13 — prime

Prime	2	8	13	Highest power
2	2	2³	—	2³
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 = 2³ × 13 = 104
