There is none because Least Common Denominator (or LCD) refers to the Least Common Multiple (LCM) of the denominators of two or more fractions or mixed numbers. Even if you converted your whole numbers (x) to their fraction equivalents (x/1), the LCD would always be 1.

You can find a common denominator of any set of denominators by multiplying them together. That result will not necessarily be the lowest common denominator. Example: 1/6 and 1/9 6 x 9 = 54 and 54 is a common denominator of 6 and 9, but the LCD is 18.
