Your teacher will grade your answer to question 8 to ensure you receive proper credit for your response.
What is the greatest common factor of 52 and 78? Explain the method you used to find it.
The greatest common factor of 52 and 78 is 26. I used the prime factorization method to find the greatest common factor. I first wrote out the prime factorization of 52 and 78:
52 = 2 x 2 x 13
78 = 2 x 3 x 13
The greatest common factor is the product of the common prime factors, which in this case is 2 x 13 = 26.
