Answer

LCM of 77 and 121 is
847

First common multiples: 847; 1,694; 2,541; …

847 is divisible by both: 847 ÷ 77 = 11, 847 ÷ 121 = 7 — and 11 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 11 and of y/121 by 7.

77 = 7 × 11

121 = 112
