There can be no greatest common denominator. For supose x is the greatest common denominator. ie 24 divides x and 36 divides x. Then 2x is a common denominator and 2x > x so 2x is a greater common denominator than the greatest common denominator. That contradiction implies that there is no greatest common denominator.
In order to have a greatest common denominator, there has to be two numbers and they both have to be fractions. 60 has no greatest common denominator.
The greatest common denominator is infinite. The least common denominator is 45.

There is no greatest common denominator, for whatever figure someone comes up with for the greatest common denominator, I can always add the lowest common denominator of 66 and 93 (which is 2046) and get an even higher common denominator.
