The greatest common factor is numbers, lets say it's 12, and 8. Since 4 is the greatest you can divide 8, and 12, it is the GCF of that problem.
To find the GCF, You need to know, Can I divide the lowest number? If so, You have completed the first step. Second, You see what can be divided into both, so there's no remainder, or no decimal. The greatest common factor of this is 2.
The GCF is 2
The GCF is 54.
The GCF of 10 and 54 is 2.
The GCF is 54.
The GCF is : 54
The GCF is 4.
The GCF is 6.
gcf of 144 and 54 is 18.
The GCF is 2.
The GCF is 6.
The GCF is 1.
The GCF is 1.
