There can be no greatest common denominator. If you have a set a numbers whose least common denominator is L then 2*L, 3*L, … are all common denominators. There is no end to that sequence and so no greatest.

Since 54 is a multiple of 18, it will also be the least common denominator of the two.

Which is greater 81 over 105 or 221 over 300?

Convert both to decimal, and compare. For example, divide 81 / 105, and write down the decimal equivalent; the same for the other fraction. OR: Find a common denominator, and convert both to the common denominator. It need not be the least common denominator; any common denominator will do - for example, if you multiply 105 x 300, you have a common denominator (which is not the least common denominator in this case). The decimal method is much easier, by the way.
