Tale a look at what this loop is doing. Think about its purpose. If you werre doing this with paper and pencil would you really use iteration?

Something tells me that I need to use > iteration, but I am not sure how I could implement it. The loops are implementing a mathematical function which doesn't need a loop. Look at the division and modulo operators.
