There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
20 and 14 are both integers. The common denominator of 20/1 and 14/1 is 1. The least common multiple is 140.
84/14 = 6 84/7 = 12 84/3 = 28 Hence 84 is the least common denominator
