Edit: The abundance is 0.953977 at 1e7 and 0.991091 at 1e8, so I think this exponent is a winner! I'll confirm tomorrow.
I ran it to 2.5e8, and that's all it needed.

$ time ./powerTrialFactoring 3 -x k.txt -l 250000000 -t 8 > output.txt  

real    51m17.165s
user    316m13.391s
sys     0m0.268s

$ grep -F "abundant" output.txt
Index 1 of 3^364[... omitted ...]125 is abundant! (1.00189)
