What is the LCM of 16, 32 and 40?

What's the Least Common Multiple (LCM) of 16, 32 and 40?

Answer

LCM of 16, 32 and 40 is

160

First common multiples: 160, 320, 480, …

160 is divisible by all three: 160 ÷ 16 = 10, 160 ÷ 32 = 5, 160 ÷ 40 = 4 — and 10, 5 and 4 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/16 by 10 and of y/32 by 5 and of z/40 by 4.

16 = 2⁴

32 = 2⁵

40 = 2³ × 5

Prime	16	32	40	Highest power
2	2⁴	2⁵	2³	2⁵
5	—	—	5	5

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

LCM = 2⁵ × 5 = 160
