press the green flag or space to calculate the GCF of two numbers. I think that the organization of the scripts is such that it is easy to understand the different components when downloaded. If you want to use some of the components (you could remove the ones dealing with deletion and input if you want to remove the GUI portion for use in a mathematical calculation that is part of a larger thing) I think this would be found very useful in games. it calculates the prime factorization and the gcf. anyone can use it if they give credit.
