What's the Least Common Multiple (LCM) of 2, 4 and 16?

Answer

LCM of 2, 4 and 16 is

16

First common multiples: 16, 32, 48, …

16 is divisible by all three: 16 ÷ 2 = 8, 16 ÷ 4 = 4, 16 ÷ 16 = 1 — and 8, 4 and 1 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 8 and of y/4 by 4.

2 — prime

4 = 2²

16 = 2⁴
