1(78 + 72)
2(39 + 36)
3(26 + 24)
6(13 + 12)
The correct answer is 6(13 + 12).
To rewrite 78 + 72 as a product using the greatest common factor, you can start by finding the greatest common factor (GCF) of 78 and 72, which is 6. Then, you can factor out the GCF from both terms and rewrite it as a product.
Therefore, 78 + 72 can be written as:
6(13 + 12)
To write 78 + 72 as a product using the greatest common factor, you need to find the greatest common factor of 78 and 72 and then express it as a product with the sum inside.
To find the greatest common factor of 78 and 72, you can use the method of prime factorization.
Prime factorization of 78: 2 × 3 × 13
Prime factorization of 72: 2 × 2 × 2 × 3 × 3
To find the greatest common factor, look for the common prime factors and multiply them together. In this case, the common prime factors are 2 and 3.
Greatest common factor: 2 × 3 = 6
Now, you can rewrite the expression 78 + 72 as a product using the greatest common factor:
6(13 + 12)
So, the correct expression using the greatest common factor as a product is 6(13 + 12).
