Final answer:
The sum of 56 + 64 expressed as a product of their greatest common factor (GCF) and another sum is 8X(7+8)=8X15. This format simplifies the sum by factoring out the GCF and representing it as a product alongside the sum of the reduced numbers.
Step-by-step explanation:
To express the sum of 56 and 64 as a product of their greatest common factor (GCF) and another sum, you first identify the GCF of the numbers 56 and 64, which is 8. To obtain the sum of 56 and 64, you divide each number by their GCF: 56 ÷ 8 = 7 and 64 ÷ 8 = 8. This translates the original numbers into multiples of their GCF, resulting in 8 times the sum of 7 and 8, as indicated by 8X(7+8).
Therefore, the product of the GCF (8) and the sum of the quotients (7+8) yields 8X15, providing the sum of 56 and 64 in a format where it's expressed as the product of their GCF and another sum.
