How do you solve 6 factorials?

Observe the numbers and their factorial values given in the following table. To find the factorial of a number, multiply the number with the factorial value of the previous number. For example, to know the value of 6! multiply 120 (the factorial of 5) by 6, and get 720.

## How do you solve 4 factorials?

4! = 4 × 3 × 2 × 1 = 24. 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040.

How do you write a factorial?

In more mathematical terms, the factorial of a number (n!) is equal to n(n-1). For example, if you want to calculate the factorial for four, you would write: 4! = 4 x 3 x 2 x 1 = 24.
