Factorial of 10

We write the factorial of a number using an exclamation mark (!) after it.

If n is a natural number greater than or equal to 1, then: n! = n × (n - 1) × (n - 2) × (n - 3) × … × 3 × 2 × 1

To find the factorial of 10, we write it as: 10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 3,628,800.

Therefore, the factorial of 10 is 3,628,800.

• Factorial: The way of multiplying all the natural numbers smaller than the original number is known as factorial, and it is expressed with an exclamation mark (!).

• Natural numbers: Counting numbers from 1, 2, 3, and so on.

• Permutations: Arrangements of objects in a specific order, often calculated using factorials.

• Combinations: Selections of objects without regard to order, often calculated using factorials.

• Million: A number equal to 1,000,000, which is important in understanding the magnitude of factorials like 10!.
