College Prep Algebra, GCF and Factor By Grouping

A great resource for any math teacher covering multiples, factors or square roots; this worksheet walks young mathematicians through the logic behind factoring and square roots with a systematic set of problems which gradually increase...

Sal explains that the greatest common factor of any number is the largest number divisible into both monomials and not necessarily the number with greatest value. He breaks down two numbers into their prime factors as a product of its...

Use division and factoring to determine the leading 1 coefficient. This presentation thoroughly explains how to factor a trinomial in order to determine its common factors.

When one method isn't enough to teach GCF, try two! This interactive webpage introduces factors and the prime factor tree to find the greatest common factor of two numbers. After the lesson, have learners click to try the two examples...

There are four terms in this polynomial. Try to factor it by grouping the terms. Confused? Try to get four terms into the product of two binomials? Still confused? Watch the instructor as she goes through the steps to group and regroup...

Here's a quick review on how to use a prime factor tree to find the greatest common factor of two numbers. This is one of the simplest ways to find the greatest common factor. So watch this video to get a refresher on how to do prime...

Put fractions with different original denominators in order using the least common denominator. Once she has shown how to find the least common denominator, an instructor constructs equivalent fractions that are more easily compared to...

Introduce your class to the greatest factor on earth. The group of videos introduces factoring polynomials by finding the greatest common factor (GCF). They connect finding the GCF of the terms in a polynomial to finding the GCF of two...

An example of factoring by grouping is shown in this video. We look at a polynomial with six terms, by grouping the terms into two trinomials with common factors. Then we factor a couple times so that we factor completely.
