The GCF is 28.
The GCF of 16, 28 and 56 is 4.
The GCF is 8.
The GCF is 28.
The GCF of 20, 28, and 56 is 4.
The GCF is 28.
The gcf of 56 and 48 is 8. The lcm of 56 and 48 is 336.
The GCF is 4.
GCF(56, 28, 14) = 14.
The GCF of 16, 28 and 56 is 4.
The GCF is 8.
GCF(56, 28, 14) = 14.
The GCF is: 8
The GCF is 4.
The GCF is 8.
The GCF is 8.
Since 28 is a factor of 56, it is automatically the GCF of this problem.
