Answer

LCM of 33 and 77 is
231

First common multiples: 231, 462, 693, …

231 is divisible by both: 231 ÷ 33 = 7, 231 ÷ 77 = 3 — and 7 and 3 share no factor but 1, so no smaller number is. As a common denominator: multiply the top and bottom of x/33 by 7 and of y/77 by 3.

33 = 3 × 11

77 = 7 × 11
