10! (the factorial of 10) is 3,628,800.
10! (the factorial of 10) is 3,628,800.
The factorial of a whole number n is the product of every whole number from n down to 1.
10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 3,628,800
10! has 7 digits. Factorials grow very quickly: each step multiplies by a bigger number than the last, so 10! is 10 times larger than 9! (362,880).
Many calculators show the result in scientific notation for large factorials.
