The greatest common denominator of any two or more whole numbers, such as 10 and 25, will always be one (1) because common denominators refers to the denominators of two or more fractions or mixed numbers, not whole numbers. So, a set of whole numbers (x,x) would have to be converted to their fraction equivalents, i.e., x/1, which will always yield a denominator of 1.
