  1. Given that \(a = 645\) and \(b = 255\), complete the table in the answer booklet to show the results obtained at each step when the algorithm is applied.
  2. Explain how your solution to part (a) would be different if you had been given that \(a = 255\) and \(b = 645\).
  3. State what the algorithm achieves.
