This twelve-question practice sheet covers prime and composite numbers, factors, common factors, and greatest common factor. Useful as guided practice, independent practice, homework, or assessment! The problems in the left-hand column mirror those in the right-hand column, so you could use one side as guided practice and the other as independent practice. A modified version (marked with an "m" in the bottom corner) is also included which is suitable for students learning English, students requiring modifications, or any student needing a little extra help.
Also included is a vocabulary sheet with examples (factors, prime number, composite number) and a reference sheet explaining two methods of finding the GCF (listing all factors and using upside-down division).
