Final answer:
The greatest common factor of 35 and 15 is 5.
Step-by-step explanation:
The greatest common factor (GCF) of 35 and 15 is 5.
To find the GCF, we need to determine the largest number that divides both 35 and 15 without leaving a remainder. We can start by finding the factors of each number:
- The factors of 35 are 1, 5, 7, and 35.
- The factors of 15 are 1, 3, 5, and 15.
The common factors are 1 and 5. The greatest common factor is 5, which is the largest number that divides both 35 and 15.
