Any idea how to open these?

I downloaded a bunch of files in a torrent file but I have no idea how to open them, I can get a part of the iso out but then it says "CRC failed in 'lfc-hmil.iso'. File is broken.". The files are;
lfc-hmil.001
lfc-hmil.002
lfc-hmil.003
lfc-hmil.004
lfc-hmil.005
lfc-hmil.006
lfc-hmil.007
lfc-hmil.008
lfc-hmil.009
lfc-hmil.010
lfc-hmil.011
