Bot GPT 3.5 To find the Greatest Common Factor (GCF) of 20x - 4, we need to factor the expression.
First, we can factor out the greatest common factor of the numerical coefficients, which is 4.
20x - 4 = 4(5x - 1)
Now, we need to see if there are any common factors between the terms inside the parentheses.
There are no common factors between 5x and -1.
Therefore, the GCF of 20x - 4 is 4.
