I'd be interested in seeing how these factors were found. My factoring program found 3597751 and 28707251, but got only as far as 56531057 in trial divisors of the remaining 76379660648003781777292087596491819833721077266601195001, which is nowhere near the needed 4032808198751 for the next prime divisor.
But, BTW, the final "prime" factor listed, 4687045214139234043375683501, also fails the prime test, the P value being 60895742403057891673741119:
list
10 N=4687045214139234043375683501
20 for Dvsr=12345 to 99999
30 if N @ Dvsr = 0 then print Dvsr:cancel for:goto *Found
40 P=modpow(Dvsr,N1,N)
50 if P<>1 then print "not prime":print Dvsr:print P:cancel for:goto *Npr
ime
60 next
65 print "couldn't prove"
70 *Found
80 *Nprime
90 end
OK
run
not prime
12345
60895742403057891673741119
OK
