Answer

LCM of 66 and 84 is
924

First common multiples: 924; 1,848; 2,772; …

924 is divisible by both: 924 ÷ 66 = 14, 924 ÷ 84 = 11 — and 14 and 11 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/66 by 14 and of y/84 by 11.

66 = 2 × 3 × 11

84 = 22 × 3 × 7
