fbncsieve v1.3.1, a program to find factors of k*b^n+c numbers for fixed b, n, and c and variable k
Sieve started: 5e13 < p < 1e14 with 159895 terms
p=50055611474419, 28.92M p/sec, 4 factors found at 15298 sec per factor, 0.1% done. ETA 20180222 16:51
Since program run only 147 seconds I assume there will be 15.298 sec per factor not 15298 per factor , but this is cosmetic bug.
+/ side works perfectly
THANKS!
