What is the least common denominator of 4 and 5?

Answer 1

There is none because the 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.

Answer 2

The least common denominator of 4 and 5 is the smallest multiple that both numbers share. In this case, the least common denominator of 4 and 5 is simply their product, which is 20. This is because 20 is the smallest number that is divisible by both 4 and 5 without leaving a remainder.

Answer 3

The LCD of -5 and 4 is 20.
