It is not possible to give a sensible answer to this question. The common denominator refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
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.
3
The greatest common denominator of any set of denominators is infinite.
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.
