Pembahasan : ✿
Faktorial adalah sebuah perkalian berulang sampai angka habis yaitu ×1 di lakulan hitung mundur , faktorial di tandai dengan ( ! )
Contoh :
- 3!
- = 3 × 2 × 1
- = 6 × 1
- = 6
- 4!
- = 4 × 3 × 2 × 1
- = 12 × 2 × 1
- = 24 × 1
- = 24
- 5!
- = 5 × 4 × 3 × 2 × 1
- = 20 × 3 × 2 × 1
- = 60 × 2 × 1
- = 120

8!
= 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 56 × 6 × 5 × 4 × 3 × 2 × 1
= 336 × 5 × 4 × 3 × 2 × 1
= 1.680 × 4 × 3 × 2 × 1
= 6.720 × 3 × 2 × 1
= 20.160 × 2 × 1
= 40.320 × 1
= 40.320

12! – 6!
= ( 12.11.10.9.8.7.6.5.4.3.2.1 ) – ( 6.5.4.3.2.1 )
= ( 12.11.10.9.8.7.6.5.4.3.2.1 ) – ( 30.4.3.2.1 )
= ( 12.11.10.9.8.7.6.5.4.3.2.1 ) – ( 120.3.2.1 )
= ( 12.11.10.9.8.7.6.5.4.3.2.1 ) – ( 360.2.1 )
= ( 12.11.10.9.8.7.6.5.4.3.2.1 ) – ( 720.1 )
= ( 12.11.10.9.8.7.6.5.4.3.2.1 ) – 720
= 479.001.600 – 720
= 479.000.880
