## What is a Perfect Number?

A number is said to be perfect the if the sum of all the factors of the number excluding the number itself results in the same number. To find whether a numer is perfect or not, first of all list all the factors of the number, excluding the number. Add all the numbers and check if it is equal to the number itself. If yes, then we can call it as a perfect number. Let us understand this better by looking at an example below.

**Solved Examples on Perfect Number Calculator**

**Example 1:**

Check whether '6' is a perfect number?

**Solution:**

Factors of 6 = 1, 2, 3, 6

Sum of factors excluding 6 is 1 + 2 + 3 = 6.

Here the sum of the factors of 6 excluding is 6.

Therefore 6 is a perfect number.

**Example 2:**

Check whether '8' is a perfect number?

**Solution:**

Factors of 8 = 1, 2, 4, 8

Sum of factors excluding 6 is 1 + 2 + 4 = 7.

Here the sum of the factors of 8 excluding is 7.

Therefore 8 is not a perfect number.

**Example 3:**

Check whether '24' is a perfect number?

**Solution:**

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24

Sum of factors excluding 6 is 1 + 2 + 3 + 4 + 6 + 8 + 12 = 36.

Here the sum of the factors of 24 excluding is 36.

Therefore 24 is not a perfect number.
