The greatest common factor (GCF) for 15, 60, and 120 is 15. To find the GCF, you need to determine the factors of each number and identify the largest number that divides evenly into all three numbers. In this case, the factors of 15 are 1, 3, 5, and 15; the factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60; and the factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. The largest number that is a factor of all three numbers is 15, making it the GCF.
The GCF of 45, 60 and 120 is 15.
The GCF is 15.
The greatest common factor of 60 and 120 is 60.
The GCF is 60.
The GCF is 60.
The GCF is 12.
Since 60 is a factor of 120, it is automatically the GCF.
The greatest common factor (GCF) of 120 and 135 is 15.
Since 15 is a factor of 120, it is automatically the GCF.
The GCF of 120 and 300 is 60.
Since 15 is a factor of 60, it is automatically the GCF.
The GCF of 60, 96, and 120 is 12.
