Find the GCF of 20x-4
To find the greatest common factor (GCF) of 20x-4, we need to determine the largest factor that can divide both 20x and 4.
First, let's factor out the common term of 20x and 4, which is 4:
20x - 4 = 4(5x - 1)
Now, since there are no common factors other than 1 between 5x and 1, the GCF of 20x-4 is 4.
