Figured it out. I got it pretty quickly too. I'd expect more people to get it.

You can disregard the 0 and use only 1,2,720!

I guess if you know that 720!=(6!)! then it may inspire you to think along using multiple factorials .

1!
2!!
3!!!
4!!!! etc .

Is that 720 or 720!?

Nevermind I read spoilers to see that 720! is correct.
