GCF of Monomials

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

In this Algebra II/college level worksheet, students factor polynomials by pulling out the GCF and by grouping.  The two page worksheet contains seventy–two problems.  Answers are provided. 

Give the class a prime example of using prime numbers. After reviewing prime factorization of numbers with the video, pupils use their knowledge to determine greatest common factors and least common multiples in the worksheet. The...

Work your way through factoring polynomials with a worksheet that starts with the GCF and ends with factoring by grouping. Each page provides an example as well as an answer key for each section. 

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.

Model how to find the greatest common factor of monomial expressions with a video that works through three examples. The first is a constant, the second a single variable expression, and the third is a multivariable example.

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...

Multiply two monomial rational expressions and then rewrite the solution in simplest form. Multiplying seems straightforward, but what about the reducing part? Find the greatest common factor. Then divide the numerator by the GCF, and...

Shortcut the work in finding total volumes. Pupils determine a polynomial expression that would represent the combined volume of three boxes. Each box has the same height, and the scholars rewrite the expression by factoring out the...
