The common denominator of any two or more whole numbers, such as 27 7 and 9, 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.
A common denominator is what you get when two different numbers (when you divide or multiply them) have a number in common. This always requires 2 numbers to have something to compare. 27 has the following denominators (by itself): 1, 3 (3*9=27), 9 (3*9=27) So it has a common denominator with at least any other number which is divisible by 1 (which would then be the "lowest common denominator"), 3 and 9.

A common denominator, though not the least, is 63000.

The least common denominator is 30. 9/10 = 27/30
You need at least two fractions to find a common denominator.
To subtract fractions with different denominators, first find a common denominator. In this case, the least common multiple of 9 and 4 is 36. Convert both fractions to have a denominator of 36, then subtract the numerators. 7/9 becomes 28/36 and 3/4 becomes 27/36. Therefore, 7/9 - 3/4 is equal to 28/36 - 27/36, which simplifies to 1/36.
The least common denominator (LCD) is 630.
