Find GCF Using Factor Trees 🌳

*Let’s learn how to find the greatest common factor using a factor tree!* In this video, we walk you through three examples covering finding the GCF between two or three numbers using prime factorization. Whether you’re learning how to find the greatest common factor for the first time or just need a quick review, this video is for you!

While videos are a great way to learn math, practice is also important. That’s why we include *free practice worksheets* (with answers at the end!) that go along with our videos, so you can practice what you’ve learned.
