Question

Using the GCF factor the given expression: 4m - 20

4(m - 5)
2(2m - 10)
4(m - 20)
2(2m - 20)

Answer 1

The expression 4m - 20 is factored by first finding the greatest common factor, which is 4, then dividing each term by 4. The correctly factored expression is 4(m - 5).

Step-by-step explanation:

To factor the given expression using the Greatest Common Factor (GCF), we first need to determine the GCF of the coefficients in the terms in the expression 4m - 20.

The GCF of 4 and 20 is 4. We then divide each term by the GCF and factor it out:

1. Divide 4m by 4 to get m.
2. Divide -20 by 4 to get -5.

After factoring out the GCF, the factored expression is: 4(m - 5)

The other options provided do not correctly factor out the GCF from each term in the expression.
