## Introduction to Prime Number Calculator

Prime number calculator is an online tool used to **find the prime number** from a cluster of numbers in less than a minute. Our tool evaluates the prime number and gives information on whether the given number is prime or not.

Prime numbers can be calculated easily if you use our prime calculator and get accurate results without any man-made error.

## What is a Prime Number

A prime number is an integer or whole as it is **greater than 1** and a **divisor of a number 1** or itself, which is called a prime number. The prime number has a two factor only that is 1 or itself number.

For example, 4 is not a prime number because it is divided into 1,2,4, etc, it shows it has three factors so it does not satisfy the prime number condition.

### What is the Greatest Prime Number

There are millions of prime numbers so it is difficult to recognize the greatest prime number from all but according to a recent discovery, 2^{24},862,048 is the greatest prime number.

### What is a Smallest Prime Number

Whether a prime number is small or large it has two factors only. As 1 is the smallest number in natural numbers it does not have two factors only so 1 is a composite number. The second **smallest number is 2** which is divisible with 1 and itself so it is the smallest prime number.

## How to Calculate a Prime Number using Prime Calculator

Prime numbers can easily be found if you know the **basic principle for prime numbers** followed by the prime number calculator. Let us explain the method of finding numbers with an example in steps and understand how the tool works.

For **example**, Find 45 a prime number or not?

**Step 1**:

The prime number solver Write down the number 45 and find all the factors of 45.

**Step 2**:

After finding all the factors of 45, it counts the factors.

**Step 3**:

If factor has two elements that is 1 and itself a number (it is a necessary condition for prime number) otherwise the given number is not prime.

**Step 4**:

The given number 45 ( 1,3,5,9,15,45 ) has 6 factors so it does not satisfy the necessary condition. That means 45 is not a prime number.

## Solved Example for Prime Number

Let's see an **example of a prime number** question to understand the working machanism of prime number calculator

### Example:

Find 30 is a prime number.

**Solution**:

$$ Factor\; of\; 30\; are\; 1,2,3,5,6,10,15,30 $$

For prime number a number must have two factors only but 30 have more than two factors.

Therefore 30 is a composite number not a prime number

### Example:

Find 48 is prime number?

**Solution**:

$$ Factor\; of\; 48\; are\; 1,2,3,4,6,12,24,48 $$

For prime number a number must have two factors only but 48 have 8 factors that is more than two factors.

Therefore 48 is a composite number not a prime number
