Training Tools are single player only when they come out , last I checked <| sep |> Look at your Euclidean Algorithm . You should have 3525737 x 6 as the first step after a rearrangement . Plug that in for that extra 35 . Edit Also , your book is either wrong or you had a typo , 1257 x 1837 x 125 . <| sep |> Not really . I was born in Germany , went to a very demanding high school staffed with nuns no , we didn ' t have religious indoctrination and teachers who forced us to think critically , critique , get deeper than just surface learning basically question everything ! We didn ' t have a problem discussing the Nazi era their deeds their lingering influence at all levels of government and private life . It ' s not like the Persilschein magically cleansed lowlevel Nazis of their sins . It was simply to keep the country running at a basic level . It was recognition that we can ' t fireexecute all of them , so the least implicated corrupt without blood on their hands ones got that Persilschein . Persil . the cleaner ! The German gov , after initially being slow and getting some serious resistance from the last holdovers of that defeated regime to get started , did at last get involved in investigating Nazi crimes and blatant miscarriages of judgments in the courts , for example . Remember , right after the war , there was no real strong German federal government but above all , not much interest by the occupiers in anything that might help Germany get back to some life not involving steal coal . They would have being happy implementing anything by Morgenthau just to show those uppity Germans . Now , that was ages ago , but today Nazi jokes elicit an uneasy polite laugh . make you feel good that YOU did not fall for that Nutcase . they have no real policies other than prey on people ' s econ insecurities and truly unworkable other stuff .
