This handout gives students practice finding the greatest common factor of a pair of numbers. Many times in my class, after we have learned about this concept, students need release time to practice the concept and build their independence. This handout has simple directions to remind students how to find the GCF. It also includes an example on how to solve a problem so students have a resource to look back to while working. This handout also comes with an answer key. You can use this in class or for a homework assignment!
