This is a form that I use when teaching GCF. Students find the GCF using a triad - groups of 3 students work together to enforce the concept by finding the greatest common factor using three different methods: factor trees, the "upside-down cake", and by using a factor tower.
Students practice each method by rotating through the sequence for each set of factors. For the first set, Student A might work using factor trees, Student B uses the cake method, etc. Then for the second set of factors, Student A uses the cake method, Student C uses factor trees, and so on.
This worksheet is a concise, attractive form for students to use to keep their triad work together.
