Best Answer

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.

### What is the lowest common denominator of the numbers 7 9 and 13?

A single number cannot have a lowest common denominator because "common" refers to multiples that two or more numbers have in common. You have only one number.

### How do you minus fractions?

First, you have to have a lowest common denominator. Eg: 1/2 - 6/13 The lowest common denominator is 26, because 13 * 2 is 26. You multiply 1/2 by 13, to make the denominator 26, which equals 13/26, then multiply 6/13 by 2 to get 12/26. So the equation with the lowest common denominators now plugged in is: 13/26 - 12/26 Subtract the numerators (13 and 12), so the answer is 1/26.

### What is the common denominator of 9 and 13?

The common denominator of 9 and 13 is 1

### What is the lowest common denominator of7 9 13?

The lowest common denominator of any two or more whole numbers, such as 7 9 and 13, will always be one (1) because 'common denominator' refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.

### How do you divide to find an equivalent fraction?

Divide the numerator and the denominator by their greatest common factor to reduce to its lowest equivalent fraction. For example, 169/260=13/20 after dividing the numerator and the denominator by 13.
