Find the GCF of 20x − 4.

The greatest common factor (GCF) of 20x - 4 is 4.

To find the greatest common factor (GCF) of 20x - 4, we need to factor both terms.

First, we can factor out 4 from both terms:

20x - 4 = 4(5x - 1)

Now, we have 4 multiplied by the expression (5x - 1).

The GCF of 20x - 4 is 4.

To find the greatest common factor (GCF) of 20x - 4, we need to factorize the expression.

The given expression is 20x - 4.

First, we can take out the greatest common factor of 4 from both terms:

4(5x - 1).

Now, we can see that there are no other factors common to both terms. Therefore, the GCF of 20x - 4 is 4.

So, the GCF of 20x - 4 is 4.
