Alyssa is preparing identical fruit baskets. There are 36 oranges and 60 apples to use for the baskets. What is the greatestnumber of fruit baskets she can prepare using all of the oranges and apples?

If you factor each number into its prime factors, you'll get:

36 = 2 x 2 x 3 x 3
60 = 2 x 2 x 3 x 5

Both numbers can be divided by 2 (twice), and 3 (once each).

Can you figure out the greatest common divisor now?
