Question

A machine at a lumberyard cuts long boards into shorter boards of a certain length. The boards that are fed into the machine come in lengths of 48 feet and 36 feet. What is the longest length of board, in feet, that the machine could cut if no wood is to be wasted on either the 36-foot or 48-foot boards?

Answer 1

To find the longest board possible without wasting any from either length, we need to find the GCF (Greatest Common Factor). In my video, I talk about how to do that in a way that you should be able to apply to any problem.

Answer 2

12 feet. Both 36 feet and 48 feet are divisible by 12.
