Final answer:
The GCF of the terms 56x, 40y, and 48z in the expression 56x + 40y - 48z is 8. Therefore, the expression can be written as the product of the GCF: 8(7x + 5y - 6z).
Step-by-step explanation:
To find the greatest common factor (GCF) of the terms 56x, 40y, and 48z in the expression 56x + 40y - 48z, we need to factor out the common factors of the coefficients of x, y, and z.
The common factors of 56, 40, and 48 are 8 and 4. The GCF of x, y, and z is 1.
Therefore, the expression 56x + 40y - 48z written as a product of the GCF is 8(7x + 5y - 6z).
