= (7 × 6 × 5 × 4 × 3 × 2 × 1)
= (42 × 5 × 4 × 3 × 2 × 1)
= (210 × 4 × 3 × 2 × 1)
= (840 × 3 × 2 × 1)
= (2.520 × 2 × 1)

= 5.040
2.) 12!
= (12 × 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)

= (1.320 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)
= (11.880 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1)
= (95.040 × 7 × 6 × 5 × 4 × 3 × 2 × 1)
