The common denominator of any two or more whole numbers, such as 28 and 32, will always be one (1) because 'common denominator' 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.

Form a common denominator which is usually the lowest common multiple of the denominators or, if this cannot be readily determined, use the product of the denominators. Convert one or more of the fractions into equivalent fractions having the common denominator as the new denominator. 15/16 + 17/32 = 30/32 + 17/32 = 47/32 = 115/32 as a mixed number
28 is one what u have to do is find a number that 4 and seven go in to.
multiply the denominators

There is none because the Least Common Denominator (or LCD) is the Least Common Multiple (LCM) of the denominators of two or more fractions.
