11! (the factorial of 11) is 39,916,800.
11! (the factorial of 11) is 39,916,800.
The factorial of a whole number n is the product of every whole number from n down to 1.
11! = 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 39,916,800
11! has 8 digits. Factorials grow very quickly: each step multiplies by a bigger number than the last, so 11! is 11 times larger than 10! (3,628,800).
Many calculators show the result in scientific notation for large factorials.
