Answer 1

To find the greatest common factor (GCF) of 78 and 86, we can start by finding the prime factorization of each number.

• The prime factorization of 78 is:

  • \(78 = 2 \times 3 \times 13\)

• The prime factorization of 86 is:

  • \(86 = 2 \times 43\)

Now, identify the common factors. The only common prime factor between 78 and 86 is 2.

Thus, the GCF of 78 and 86 is 2.

The correct response is 2.
