This math skill teaches how to perform factoring using a factor tree, a method where a number is broken down into its prime factors systematically. Starting from the number, each split represents its factors until only prime numbers are left at the bottom.

Explain factoring with a factor tree
Test your understanding of explain factoring with a factor tree by practicing it! Work through the below exercises to use it in practice.
🎙️
Let's look at what a factor tree means
🎙️
Each pair multiplies to the number above it
🎙️
So, at the bottom, 3 times 3 equals 9, and 2 times 2 equals 4
🎙️
Then in the middle row, 9 times 4 equals 36
🎙️
If you start from 36, and create this factor tree, the final factors are the ones that cannot be split any further. The prime factorization of 36 is 3 times 3 times 2 times 2
