The common denominator of any two or more whole numbers, such as 6 9 15 and 18, 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 of 6 and 15 is 90.
18 3*6 = 18 2*9 = 18
Answer: 30 If those numbers are denominators, the least common denominator is the least common multiple of the three. In this case, 30 is the LCM of 6, 10 and 15, so 30 is the least common denominator.

The Greatest Common Denominator is 6
18 3*6 = 18 2*9 = 18
the least common multiple of 15,9,and 12 is 180.

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.
