The sum of two numbers can be expressed as the product of their greatest common factor (GCF) and another sum by factoring out the GCF from both numbers and then expressing them as the product of the GCF and the remaining factors. In this case, the GCF of 63 and 15 is 3. Therefore, 63 + 15 can be written as the product of 3 and the sum of the factors after dividing each number by 3.

63 + 15 = 3 * (21 + 5)
