The value of 8 factorial, which is denoted as 8!, is calculated by multiplying all whole numbers from 8 down to 1.
Specifically, 8! = 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1.
Let’s break it down:
- 8 × 7 = 56
- 56 × 6 = 336
- 336 × 5 = 1680
- 1680 × 4 = 6720
- 6720 × 3 = 20160
- 20160 × 2 = 40320
- 40320 × 1 = 40320
Therefore, the value of 8! is 40320. Factorial calculations grow very large very quickly, which is why they play an important role in combinatorics and probability.
