Identify GCF: Identify the greatest common factor (GCF) of the terms 27x and 63. Both 27 and 63 are multiples of 9, so 9 is a common factor. Additionally, since there is an x in the first term, the GCF is 9 (since the second term does not have an x to contribute to the GCF).
Divide by GCF: Divide each term by the GCF to find the other factors.27x÷9=3x63÷9=7
Write as product: Write the expression as a product of the GCF and the other factors.The factored expression is 9(3x−7).
