To find the greatest common factor (GCF) of 10 and 25, we can follow these steps:
-
List the factors of each number:
- Factors of 10: 1, 2, 5, 10
- Factors of 25: 1, 5, 25
-
Identify the common factors:
- Common factors of 10 and 25: 1, 5
-
Find the greatest of these common factors:
- The greatest common factor is 5.
Thus, the GCF of 10 and 25 is 5.
