What is the greatest common factor of 10, 30, and 45
The greatest common factor (GCF) of 10, 30, and 45 is 5.
To find the GCF, you can list the factors of each number:
Factors of 10: 1, 2, 5, 10
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 45: 1, 3, 5, 9, 15, 45
Then, you can identify the factors that all three numbers have in common. In this case, it is only the factor of 5. Therefore, the GCF is 5.
