Example of Factorial

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

Proof
From $21$ Factorial:
 * $21! = 51 \, 090 \, 942 \, 171 \, 709 \, 440 \, 000$

Then: 51 090 942 171 709 440 000 x                         22 - 102 181 884 343 418 880 000 1 021 818 843 434 188 800 000 - 1 124 000 727 777 607 680 000
