There are two fractions written on the blackboard: (17/2012), (19/1509), and the operation is as follows: replace the large number with the difference between the two numbers (large number minus the number) to get two new numbers. Repeat the same operation until the same two numbers appear. What is the last two numbers that appear the same?
