Find the GCF of 20x − 4. (1 point)

Answer 1

To find the greatest common factor (GCF) of the expression \(20x - 4\), we can factor out the common factor from both terms.

1. The coefficients are 20 and -4. The GCF of the numbers 20 and 4 is 4.
2. We can also factor out 4 from the expression:

\[ 20x - 4 = 4(5x - 1) \]

Thus, the GCF of the expression \(20x - 4\) is \(4\).
