Identify GCF: Identify the greatest common factor (GCF) of the two terms in the expression 48x3z4 and −44x6yz3. The GCF is the product of the lowest powers of common factors. Both terms have a common factor of 4, x, and z. The lowest power of x common to both terms is x3, and the lowest power of z is z3. Calculate the GCF: 4×x3×z3=4x3z3.
Calculate GCF: Factor out the GCF from the original expression.Divide each term by the GCF to find the remaining factors.4x3z348x3z4=12z and 4x3z3−44x6yz3=−11x3y.Write the factored expression as the GCF multiplied by the remaining factors: 4x3z3(12z−11x3y).
Factor out GCF: Check the factored expression to ensure that when it is expanded, it results in the original expression.Multiply the GCF by each term in the parentheses: 4x3z3×12z=48x3z4 and 4x3z3×−11x3y=−44x6yz3.Combine the two products to confirm that they equal the original expression: 48x3z4−44x6yz3.
