Answer

LCM of 16, 28 and 44 is
1,232

First common multiples: 1,232; 2,464; 3,696; …

1,232 is divisible by all three: 1,232 ÷ 16 = 77; 1,232 ÷ 28 = 44; 1,232 ÷ 44 = 28 — and 77, 44 and 28 have no factor but 1 common to all of them, so no smaller number is. As a common denominator: multiply the top and bottom of x/16 by 77 and of y/28 by 44 and of z/44 by 28.

16 = 24

28 = 22 × 7

44 = 22 × 11
