What is factorial?
The factorial of a whole number is the function that multiplies the number by every natural number below it. Symbolically, a factorial can be represented by using the symbol "!". So, "n factorial" is the product of the first n natural numbers and is represented as n!.
So n! or "n factorial" means:
n! = 1 · 2 · 3 · ... · n = Product of the first n positive integers = n(n-1)(n-2)…………………….(3)(2)(1)
The formula for n factorial is: n! = n × (n - 1)!
n! = n × (n - 1)!
This means that the factorial of any number is, the given number, multiplied by the factorial of the previous number. So, 8! = 8 × 7!...... And 9! = 9 × 8!...... The factorial of 10 will be 10! = 10 × 9!...... Like this if we have (n+1) factorial then it can be written as, (n+1)! = (n+1) × n!. Let us see some examples.
Given:
Digits are: 8, 0, 1, 3, 7, and 5
There total 6 digits.
So, number of 6 digits can be made is = 6!
= 6*5*4*3*2*1
= 720
