GCF of 4 over 4 is 4.
The GCF is 1.
The GCF is 4.
Using the GCF between 4 and 72 (which is 4) you can simplify the fraction to 1/18
12/16 = 3/4 because 4 is the gcf
The GCF of 15 and 20 is 5.15/20 = 3/4
The GCF is 8. 32/40 = 4/5
The GCF of 9 and 12 is 3.9/12 = 3/4
The GCF is 4.4/8 = 1/2
Since 32 is a factor of 256, it is automatically the GCF.
The GCF of 2 and 8 is 2. 2/8 = 1/4
The GCF of 20 and 32 is 4, allowing you to simplify to 5/8
It is 1/2 because 2 is the gcf
