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.
The Least Common Multiple (LCM) of 27, 10, and 12 is 540.
The least common denominator is 30. 9/10 = 27/30
