A common factor is a number that is a factor of both (or all) the numbers in question. Therefore 55 would be a common factor of 110 and 165 because both of these numbers can be divided by 55.
However, a number by itself (and not in reference to other numbers) cannot be called a common factor. So 55 could be a common factor, but isn't necessarily always one.
