Factorial/Examples/19

Example of Factorial

 * $19! = 121 \, 645 \, 100 \, 408 \, 832 \, 000$

Proof
From $18$ Factorial:
 * $18! = 6 \, 402 \, 373 \, 705 \, 728 \, 000$

Then: 6 402 373 705 728 000 x                   19 --- 57 621 363 351 552 000 64 023 737 057 280 000 --- 121 645 100 408 832 000
