677 factors were found

For n<=2M I found 77 factors

The total time spent on sieving is:

2,000,000,000,000/1,080,000 p/sec = 1,851,851 seconds

For n<=2M I had an average time of 24,050.012 sec/factor
For n>2M to n<=5M I had an average time of 14,467.586 sec/factor
For n>5M I had an average time of 3,923.413 sec/factor
