What's the Least Common Multiple (LCM) of 3, 5 and 16?

Answer

LCM of 3, 5 and 16 is
240

First common multiples: 240, 480, 720, …

240 is divisible by all three: 240 ÷ 3 = 80, 240 ÷ 5 = 48, 240 ÷ 16 = 15 — and 80, 48 and 15 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/3 by 80 and of y/5 by 48 and of z/16 by 15.
