The greatest common factor (GCF) of 45 and 26 is 1.
To find the GCF, we can start by determining the factors of each number:
- Factors of 45: 1, 3, 5, 9, 15, 45
- Factors of 26: 1, 2, 13, 26
Next, we identify the common factors between the two sets:
- Common factors: 1
Since 1 is the only common factor, we conclude that the greatest common factor of 45 and 26 is 1. This indicates that 45 and 26 are relatively prime, meaning they do not have any other common factors besides 1.
