The GCF is: 2
The GCF is 2.
The GCF is 2.
The GCF of 28 and 30 is 2. The GCF of 30 and 28 is 2 because if you divide them each by 2, then you are left with 15 and 14 and they don't share any factors other than 1.
The GCF of 12, 28, and 30 is 2
The GCF is 4.
The GCF is 2.
The GCF is 2.
The GCF is 1.
The GCF is 28.
The GCF would be 4.
The GCF is 4.
First you have to find the GCF (Greatest Common Factor) of 28 and 30, which is 2, so then you divide 2 by 28 and 30, and get 14 over 15. Hoped this helped!
