ON. May 1, 2004 USAMO Graders: Back Row: David Wells- AMC 12 Chair, Titu Andreescu- USAMO Chair, Razvan Gelca, Elgin Johnston- CAMC Chair, Zoran Sunik, Gregory Galperin, Zuming Feng- IMO Team Leader, Steven Dunbar- AMC Director. Front Row: David Hankin- AIME Chair, Kiran Kedlaya, Dick Gibbs, Cecil Rousseau, Richard Stong. USAMO Grading, 1An alternative approach for students who know Euler’s theorem is to simply notice ’(220) = 219, where ’ is the Euler phi function. Therefore 5219 1 (mod 220) and so 5219+20 520(mod 220). The hands-on proof gives a tad more; since 5 211 = 22, in fact 2 divides 5191, not just 220. 5.
