Why does the DB say that this number is 2*324*1918*363889*109912203092239643840221 instead of 2*318*1918*363889*109912203092239643840221? I checked in Pari/gp, and it says this: Code: (18:11) gp > factor(3226950014783883023598007090793710151258504258637092076077562) %1 = [ 2 1] [ 3 18] [ 19 18] [ 363889 1] [109912203092239643840221 1] (18:11) gp > 2*3^18*19^18*363889*109912203092239643840221 %2 = 3226950014783883023598007090793710151258504258637092076077562 (18:17) gp > Somehow, the db messed up on the power of 3, and reports the factorization of this number instead. Last fiddled with by Stargate38 on 2017-03-17 at 22:26 Reason: 109912203092239643840221 instead of (19^19-1)/18 for clarity...
