n !=100 !
n !=1*2*3*4*.....*n
Ex: factorial 2 !=1*2=2
3 !=1*2*3=6
4 !=1*2*3*4=24
5 !=1*2*3*4*5=120
6 !=1*2*3*4*5*6=720
7 !=1*2*3*4*5*6*7=5040
8 !=1*2*3*4*5*6*7*8=40230
9 !=1*2*3*4*5*6*7*8*9=362880------------etc..........
362880*10=3628800 .........=> factorial 10 !...
3628800*11=19916800.......=> factorial 11 !
factorial 11*12= factorial 12 !....inmultit cu 13=> factorial 13 ! ...
inmultit cu 14 => factorial 14 ! .....* n= n!
Factorial 100 ! = 1*2*3*4*5*6*7*8*9*.....*100 = 9332621544e157
