0 cannot be the denominator, but all numbers can be in the denominator.
If the whole denominator equals 0 (so things like 3+0 or y+0 wouldn't count) then the fraction's value is undefined since no number can be divided by 0 and give one answer. But if the question is exactly as it is phrased, there is no number that can never be in the denominator.

There is really no such thing as a "greatest common denominator". Once you find the least common denominator of a set of numbers, you can keep adding the LCD to itself over and over again. Each new number you get will be a common denominator of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest denominator.There is really no such thing as a "greatest common denominator".

zero can not be a denominator.
A Denominator. no problemo...The denominator.
The numerator is the top number, the denominator is the bottom number. I always remembered that the "denominator" was "down".
Any real number can be the denominator in a fraction. A fraction is a way of expressing one number (the numerator, the "top" number in a fraction) by another (the denominator, "bottom number.") So it is possible to have a denominator of 100.
