Prime Number Calculator

Prime Number is an integer or whole number, that cannot be made by multiplying other whole numbers. It is also defined as greater than 1 that is only divisible by 1 and itself. In simple words, a prime number has only two factors, 1 and itself. If the number is not divisible by 1 and itself then it is called a composite number.

Examples:

1. Is 1 prime or not? 1 is neither prime nor composite as it has only one factor (itself).
2. Is 46 a prime number? No, 46 is NOT a prime number because it has more than two factors. 46 is a composite number and can be factored by any of the following numbers: 1, 2, 23, 46.

To prove whether a number is a prime number or not, first, check the number by dividing with 2, and view if you get a whole number. If you get then it is not a prime number. Next, try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3), and so on, always dividing by a prime number if you don't get the whole number.

Well, there are various ways to find whether a number is prime or not. Here we are going to discuss the best method to find prime number ie., factorization method. With the help of factorization, you will avail the factors of a number and it is easy to identify a prime number.

1. Initially, you have to find the factor of the given integer.
2. Now, check the factors count of that number.
3. Finally, if you get the factor more than two for the given number then it is not a prime number.

For grasping the whole concept easily we have given the solved example on how to find the prime number in the below module. So, have a glance at the step by step guide on how to check whether a number is prime or not.

Example:

Find out if 45 is a prime number or not?

Solution:

First, you should take the given number ie., 45.

To check 45 is prime or not, first, find the factor for this integer.

The factors of 45 are 1, 3, 5, 9, 15, 45.

As per the definition, a prime number is a whole number greater than 1 that only divisible by 1 and itself.

So, here you are seeing the number 45 has more than two factors.

Thus, 45 is NOT a prime number.
