What's the Least Common Multiple (LCM) of 10, 25 and 40?

Answer

LCM of 10, 25 and 40 is
200

First common multiples: 200, 400, 600, …

200 is divisible by all three: 200 ÷ 10 = 20, 200 ÷ 25 = 8, 200 ÷ 40 = 5 — and 20, 8 and 5 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/10 by 20 and of y/25 by 8 and of z/40 by 5.

10 = 2 × 5

25 = 52

40 = 23 × 5
