What is the Greatest Common Factor (GCF)?

Back

The GCF is the largest number that divides two or more numbers without leaving a remainder.

Front

How do you factor an algebraic expression using the GCF?

Back

To factor an algebraic expression using the GCF, identify the largest common factor of the coefficients and variables, then divide each term by the GCF and express the original expression as the product of the GCF and the resulting expression.

Front

What does it mean to combine like terms in an expression?
