What is the LCM of 40 and 100?

What's the Least Common Multiple (LCM) of 40 and 100?

Answer

LCM of 40 and 100 is

200

First common multiples: 200, 400, 600, …

200 is divisible by both: 200 ÷ 40 = 5, 200 ÷ 100 = 2 — and 5 and 2 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/40 by 5 and of y/100 by 2.

40 = 2³ × 5

100 = 2² × 5²

Prime	40	100	Highest power
2	2³	2²	2³
5	5	5²	5²

LCM = 2³ × 5² = 200
