Using Factor Trees

In this factor trees worksheet, students make factor trees for 2 through 4 digit numbers. Students complete 20 factor trees for these numbers.

Find the common denominator between prime factors, factor trees, and the distributive property. Scholars learn to find the least common multiple and greatest common factor of pairs of numbers. They rotate through stations to connect...

Learners use the example of a factor tree to find the greatest common factor of three numbers in four problems.

Demonstrate a method for finding the prime factorization of numbers using factor trees and a video that explains how to break a number down to its prime factors. The instructor reinforces the concept of factors by displaying the...

Deepen the number sense of young mathematicians by exploring the process of prime factorization. Follow along with this step-by-step presentation that explains how factor trees are used to break a composite number down into its prime...

What is a prime number? Is zero a prime number? Is one a prime number? No?! Is two a prime number? Yes. So what is the definition of a prime number? A prime number is a number that can only be divided by 1 and itself. Watch this short...

Beginning with a description that sets the stage, learners are asked to break down the numbers 42 and 63 to find the greatest common denominator using factor trees. As they work through the factoring process, young mathematicians are...

The instructor defines a prime polynomial as much the same as a prime number: they only have two factors, 1 and itself. She further demonstrates what a composite polynomial is to give an example of a polynomial that is not prime.

A factor tree? What's a factor tree? A tree of factors? A factor tree is a method use to do the prime factorization of an integer. It's not complicated. Watch the teacher as she explains the steps and shows how to write the answer as a...

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...
