Example of Factorial

$23! = 25 \, 852 \, 016 \, 738 \, 884 \, 976 \, 640 \, 000$


Proof

From $22$ Factorial:

$22! = 1 \, 124 \, 000 \, 727 \, 777 \, 607 \, 680 \, 000$

Then:

 1 124 000 727 777 607 680 000
x                           23
------------------------------
 3 372 002 183 332 823 040 000
22 480 014 555 552 153 600 000
------------------------------
25 852 016 738 884 976 640 000
