What's the Least Common Multiple (LCM) of 63 and 84?

Answer

LCM of 63 and 84 is
252

First common multiples: 252, 504, 756, …

252 is divisible by both: 252 ÷ 63 = 4, 252 ÷ 84 = 3 — and 4 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/63 by 4 and of y/84 by 3.

63 = 32 × 7

84 = 22 × 3 × 7
