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.

LCD means lowest (or least) common denominator, and that implies there must be at least two fractions involved for something to be common to both of them. There is, therefore, no sensible answer to this question.

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.

The lowest common denominator of any two positive numbers is always 1.
