Paula has two pieces of wire, one 96 feet long and the other 72 feet long. If she wants to cut them up to produce many pieces of wire that are all of the same length, with no wire left over, what is the greatest length, in feet, that she can make them

If you pull the information into a mathematical context, you'll notice it is asking for the highest common factor of the 2 numbers

Let's put both of them in prime factorization:

96 = 2^5 x 3

72 = 2^3 x 3^2

Now pick out what is common in these

2^3 x 3 = 24

Thus it would be 24 feet
