Answer

LCM of 105 and 245 is
735

First common multiples: 735; 1,470; 2,205; …

735 is divisible by both: 735 ÷ 105 = 7, 735 ÷ 245 = 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/105 by 7 and of y/245 by 3.

105 = 3 × 5 × 7

245 = 5 × 72
