how are those larger than 3x10^15?

! = Factorial

Factorial means multiply the number you see by all the natural numbers below it. So 18! is:

18 x 17 x 16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

Yes the 1 is redundant. I'm including the 1. Equality for 1s!

That number ends up being about 6.4 x 10^15

And just to add, a double factorial basically skips every other number, and a triple factorial skips 2/3
So 50!!! is

50x47....

Ends up being just about 10x larger than 18! I think
