What is the value of 5 factorial or 5?
120
To find 5 factorial, or 5!, simply use the formula; that is, multiply all the integers together from 5 down to 1. When we use the formula to find 5!, we get 120. So, 5! = 120.
How do you calculate a factorial?
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.

What is the factorial value?
factorial, in mathematics, the product of all positive integers less than or equal to a given positive integer and denoted by that integer and an exclamation point. Thus, factorial seven is written 7!, meaning 1 × 2 × 3 × 4 × 5 × 6 × 7. Factorial zero is defined as equal to 1.
What is the factorial value of 0?
1
The value of 0! is 1, according to the convention for an empty product. The factorial operation is encountered in many areas of mathematics, notably in combinatorics, algebra, and mathematical analysis. Its most basic use counts the possible distinct sequences – the permutations – of n distinct objects: there are n!.
What is the factorial of 5?
Before we begin, note that the factorial of 5 can be written as 5 followed by an exclamation mark like this: 5! Factorial of 5 means that you multiply 5 by every number below it. Therefore, you calculate the factorial of 5 by multiplying 5 by 4 and then by 3 and so on all the way down to 1.
What is a zero factorial in math?
Math. A zero factorial is a mathematical expression for the number of ways to arrange a data set with no values in it, which equals one. In general, the factorial of a number is a short hand way to write a multiplication expression wherein the number is multiplied by each number less than it but greater than zero.
How do you find the factorial of 9?
The factorial function (symbol: !) says to multiply all whole numbers from our chosen number down to 1. We can easily calculate a factorial from the previous one: n! = 2 × 1! = 3 × 2! = 4 × 3! = 5 × 4! Example: 9! equals 362,880.
What is a factorial in math example?
Factorial ! The factorial function (symbol: !) says to multiply all whole numbers from our chosen number down to 1. We can easily calculate a factorial from the previous one: n! = 2 × 1! = 3 × 2! = 4 × 3! = 5 × 4!
