LCD(20, 28) = 140
So with 3 fractions with denominators of 28 21 and 15: 28 = 7 x 4, 21 = 7 x 3, and 15 = 5 x 3. 28 and 21 have 7 in common; 21 and 15 have 3 in common, so those factors are used once: 7 x 4 x 3 x 5 = 420
84/14 = 6 84/7 = 12 84/3 = 28 Hence 84 is the least common denominator
There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions. Even if you converted your numbers (x) to their fraction equivalents (x/1), the LCD will always be 1.
