Answer

LCM of 66 and 121 is
726

First common multiples: 726; 1,452; 2,178; …

726 is divisible by both: 726 ÷ 66 = 11, 726 ÷ 121 = 6 — and 11 and 6 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/66 by 11 and of y/121 by 6.

66 = 2 × 3 × 11

121 = 112
