RSA-encrypting envolves calculations of the type 489^2281 mod 3293 With maxima, I have tried factor(489^2281),modulus:3293; which yields the factors 2 13 43 Of course, I can now do 2*13*43 and get the final result, 1118. But how can I get this result directly in a one-line command? Yours, Poul Riis Lemvig Gymnasium Denmark
