To find the greatest common factor (GCF) of the expression \(20x - 4\):

  1. Identify the coefficients: The coefficients in the expression are 20 and -4.

  2. Find the GCF of the coefficients:

    • The factors of 20 are: 1, 2, 4, 5, 10, 20
    • The factors of -4 are: 1, 2, 4

    The greatest common factor of 20 and -4 is 4.

  3. Factor out the GCF from the expression:

    • Rewrite \(20x - 4\) as \(4(5x - 1)\).

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