Greatest Common Factor and Least Common Multiple (GCF & LCM) Activity FREEBIE

Make finding the GCF and LCM fun with this code-breaker game. Students are asked to find the GCF or LCM of two or three numbers. Ideal as a bellringer or quick review activity.

The code is random to avoid your students attempting to guess a riddle rather than 'do the math'!

Follow me here on TPT where I have many similar activities!

Make it more engaging by offering a small reward for the first student to crack the code. This makes a great spiral review activity.

This worksheet was clear, well-structured, and highly engaging for my students. The directions were easy to follow, and the activities were scaffolded in a way that supported different learning levels. I especially appreciated how it reinforced key concepts while still encouraging critical thinking. It worked perfectly as both classwork and review. Highly recommend for anyone looking for a ready-to-use resource
