10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= 90 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= 720 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= 5.040 x 6 x 5 x 4 x 3 x 2 x 1
= 30.240 x 5 x 4 x 3 x 2 x 1
= 151.200 x 4 x 3 x 2 x 1
= 604.800 x 3 x 2 x 1
= 1.814.400 x 2 x 1
= 3.628.800 x 1
= 3.628.800
9! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= 72 x 7 x 6 x 5 x 4 x 3 x 2 x 1
= 504 x 6 x 5 x 4 x 3 x 2 x 1
= 3.024 x 5 x 4 x 3 x 2 x 1
= 15.120 x 4 x 3 x 2 x 1
= 60.480 x 3 x 2 x 1
= 181.440 x 2 x 1
