How Do You Find the Prime Factorization of a Number Using a Tree?

Note:

To write the prime factorization for a number, it's often useful to use something called a factor tree. Follow along with this tutorial and see how to use a factor tree to find the prime factorization of a given number.

If the only factors a number are 1 and itself, then that number is prime. A number that is not prime is called composite. Learn about prime and composite numbers by watching this tutorial!

To find the greatest common factor (GCF) between numbers, take each number and write its prime factorization. Then, identify the factors common to each number and multiply those common factors together. Bam! The GCF! To see an example worked out, check out this tutorial!

In this tutorial, follow along as a monomial is written in factored form. This is information may come in handy if you ever need to simplify an expression involving monomials. Better check it out!
