While 1172889 has 15 odd factors, 1172888 only has 4. If the smallest is 1 and the largest is 146611, what are the other two?

You can do this without a calculator and with no brute force checking if you do it well.

I’m basically exclusively a standard player but I watch all the world cups. There are always a lot of terms that I don’t recognize, and mania is always the worst about this. Some of them I can decipher, like sv and ln, but some of them elude me. Besides standard, 4K World Cup is probably my favorite to watch and I think I would enjoy it even more if I understood more of these terms. Big thanks to anyone willing to help me out!

Edit: I wasn’t very clear with this but if you could let me know what the terms mean as well that would be great

I am a mostly irrelevant mappooler with enough experience to make a solid pool. A few friends asked for some help with their own pooling for some six digit tournaments and I had just finished pooling for one so I decided to throw together a guide for them. It ended up being a lot bulkier than I had originally intended so I decided to clean it up and share it here for anyone else who might want some tips. While the advice isn't irrelevant to higher rank tournaments, some of the ways certain pools are structured don't make sense when there are more complex maps available. I hope this helps somebody.
