Answer

LCM of 77 and 88 is
616

First common multiples: 616; 1,232; 1,848; …

616 is divisible by both: 616 ÷ 77 = 8, 616 ÷ 88 = 7 — and 8 and 7 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/77 by 8 and of y/88 by 7.

77 = 7 × 11

88 = 23 × 11
