The greatest common factor (GCF) of 52 and 85 is 1.
To determine the GCF, we first need to find the factors of each number:
- Factors of 52: 1, 2, 4, 13, 26, 52
- Factors of 85: 1, 5, 17, 85
Now, we compare the factors of both numbers to find the largest factor that they have in common. The only number that appears in both lists is 1. Therefore, the greatest common factor of 52 and 85 is 1. This indicates that 52 and 85 have no other common factors besides 1, making them relatively prime to each other.
