Using the greatest common factor for one term, how can you write 78+ 72 as a product?

1 answer

The greatest common factor of 78 and 72 is 6. Therefore, we can write the expression 78 + 72 as a product by factoring out the greatest common factor:

78 + 72 = 6 * 13 + 6 * 12

Now, we can factor out the common factor:

= 6 * (13 + 12)

Therefore, 78 + 72 can be written as the product 6 * (13 + 12).
