The common denominator of any two or more whole numbers, such as 27 and 99, 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.
99:33,3,99,1. 100:100,1,2,50,25,4,5,20.

945 is the lowest common denominator. 3 is the greatest common factor.
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.
135 is the lowest common denominator of numbers 27 and 45.

Since there are no common prime factors of 7 and 27, you must multiply them together to get the common denominator. 27 times 7 is 189.
