I was just taking a look into the "U" database and found a few even numbers, like this.
Why are people uploading such numbers???

Any how, that a look at he amount of factors.

Just fully factored this even number: 10^100000*3
Someone just uploaded/checked this number...rly?

That number is (10^100000-1)*2/9 and submitting that as a factor caused factordb to express it as that. Which saves a little bandwidth when looking at that page.

It also has a load of algebraic factors. Which is why it had so many small factors.
