0 Akriti Posted November 28, 2010 Report Share Posted November 28, 2010 Let the digits be x, y, and z. So the number is 100x+10y+z At last we get 100x+10y+z=x3+y3+z3 After simplifying, we get x(100-x2)+y(10-y2)+z(1-z2) After that if we put hit and trial method we will get 370,371,407 and 153 Quote Link to comment Share on other sites More sharing options...
