Find the GCF and then factor

To find the greatest common factor (GCF) of -56y and 16, we first need to find the GCF of the coefficients -56 and 16.

The factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56.
The factors of 16 are 1, 2, 4, 8, and 16.

The GCF of 56 and 16 is 8.

Now, we can factor out the GCF from the original expression -56y + 16:

8(-7y + 2)
