What's the Least Common Multiple (LCM) of 6, 12 and 14?

Answer

LCM of 6, 12 and 14 is
84

First common multiples: 84, 168, 252, …

84 is divisible by all three: 84 ÷ 6 = 14, 84 ÷ 12 = 7, 84 ÷ 14 = 6 — and 14, 7 and 6 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/6 by 14 and of y/12 by 7 and of z/14 by 6.

6 = 2 × 3

12 = 22 × 3

14 = 2 × 7
