The GCF is 5.
The GCF is 21.
The GCF is 5.
The GCF is 21.
The GCF is 2.
The GCF is 7.
The GCF of 75 and 105 is 15. This leaves you with 5 and 7 respectively after division. You can do nothing further.
The greatest common factor (GCF) of 15, 25, and 40 is 5.
The GCF is 50.
The GCF is 56.
GCF of 175 and 56 is 7.
The greatest common factor (GCF) of 45 and 56 is 1. To find the GCF, you can list the factors of each number and then identify the largest number that divides both 45 and 56 without leaving a remainder. In this case, the only common factor of 45 and 56 is 1, making it the greatest common factor.
