Description:

This problem, which acts like a function machine, provides an opportunity to also introduce children to the idea of common factors. Four whole numbers (inputs) are each placed in a small box and those boxes are placed in one special box. Solvers are given the four outcomes and are challenged to find what multiplication might have gone on in the big box to get those results. The Teachers' Notes page offers suggestions for implementation, key discussion questions, ideas for extension and support.
