Find the factorial of the given number

### Factorial of 100 is **9.332621544394418e+157 **

## What is factorial?

### Meaning of Factorial:

#### Factorial of a number is the result we get on multiplication of the given number by all numbers below it upto 1. It is only applicable to integers > 0. For eg. Factorial of 3 is equal to 3 x 2 x 1 = 6

**Notation:**

Factorial of a number is denoted by the exclamation symbol followed by the number.(x!) or Fact(x).**Factorial Formula .**#### (factorial of n) n! =n x (n-1) x (n-2) x ....1 = n x (n-1)!

### Factorial example.

1! = 1

2! = 2x1 = 2

3! = 3x2x1 = 6

4! = 4x3x2x1 = 24

5! = 5x4x3x2x1 = 120

## Simplifying factorials / Calculating factorials

### n Factorial Formula

#### As we know that we have a formula for finding the factorial of the given number.So lets see how to implement the formula and get the result.

It is**n x (n-1) x (n-2) x ....x 1****Factorial of 5**

According to our formula n =5. 5! = 5 x (5-1) x (5-2) x (5-3) x..1

5! = 5 x 4 x 3 x 2 x 1

5! = 120

## 0 Factorial / Zero Factorial

### Factorial of 0 is 1.

### Lets discuss how 0! is 1.

We know that n! = n x (n-1)! ==> n = n!/(n-1)! this means the following,**(n-1)! = n!/n**

if n = 1

it becomes 0! = 1!/1 = 1

From the above we conclude that**Zero Factorial is 1**

## Is there a Negative Factorial

### No, there is no negative factorial.

### Factorials are defined only for non-negative integers. For example, the factorial of 4 is 24, the factorial of 0 is 1, and the factorial of -1 is undefined.

### One reason for this is that factorials are used to count the number of ways to arrange or select objects. For example, there are 6! ways to arrange 6 different objects in a row. However, there is no such thing as a negative number of objects, so it does not make sense to define a factorial for a negative number.

### Another reason for not defining negative factorials is that it would lead to mathematical contradictions.

## Interesting Facts About Factorials

### Factorials can be used to calculate the number of ways to arrange a set of objects in a particular order. For example, there are 6! ways to arrange 6 different objects in a row.

### Factorials can also be used to calculate the number of possible combinations of objects from a set. For example, there are 15 ways to choose 3 objects from a set of 5 objects.

### Factorials grow very quickly, even for relatively small numbers. For example, 10! is over 3.5 million.

### The largest factorial that can be calculated on a standard computer is 170!.

### Factorials are related to the Fibonacci sequence. The Fibonacci sequence is a series of numbers where each number is the sum of the two previous numbers. The first few numbers in the Fibonacci sequence are 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ...

### Factorials can also be used to calculate the volume of a sphere.

### Factorials are used in some encryption algorithms.

### The factorial of a prime number is always greater than the prime number itself.

### The sum of the reciprocals of the factorials is equal to the natural logarithm of e, Euler's constant.

### The factorial of a number is equal to the product of all the positive integers less than or equal to that number.

## Where are Factorials Used

**Probability:**Factorials can be used to calculate the probability of certain events happening. For example, the probability of getting 3 heads in a row when flipping a coin is 1/8, which can be calculated using factorials.**Statistics:**Factorials are used in many statistical tests, such as the chi-squared test and the t-test. These tests are used to test the significance of differences between groups or to predict future outcomes.**Combinatorics:**Factorials are used in combinatorics to count the number of ways to arrange or select objects. For example, the number of ways to arrange 6 different books on a shelf is 6!.**Number theory:**Factorials are used in number theory to study the properties of prime numbers and other types of numbers.

**Computer science:**Factorials are used in many computer science algorithms, such as the quicksort algorithm and the factorial algorithm.**Finance:**Factorials are used in finance to calculate the price of options and other financial products.**Genetics:**Factorials are used in genetics to calculate the probability of inheriting certain traits.**Manufacturing:**Factorials are used in manufacturing to calculate the number of ways to assemble products.**Logistics:**Factorials are used in logistics to calculate the number of ways to route vehicles and deliver goods.
