What is the simplified square root of 15? Such numbers are called complete numbers. In fact, all the perfect numbers are also complete numbers. The four perfect numbers 6, 28, and are known to us since ancient times. Let's see their divisors and their sum through the table given below:. Perfect numbers are the special type of numbers that are less known to students as compared to the other types of numbers. In this section, you will learn how to find perfect numbers easily.

If as many numbers as those beginning from the unit be set out continuously in double proportion until the sum of all becomes a prime, then the product of the sum and the last number makes a perfect number. Double Proportion means that each number in a sequence is double the preceding number. Mersenne prime is a prime that is one less than the power of 2.

For example, Let's take N as 31 which is 1 less than 2 4. Here are a few topics that can be referred to for more information on topics related to perfect numbers. The proper factors of 28 are 1, 2, 4, 7 and The sum of proper factors is According to the definition of perfect numbers, 28 is a perfect number.

According to Euclid's proposition, if 2 p -1 is a prime number, then 2 p-1 2 p -1 is a perfect number.

Can you make a list of 8 perfect numbers using this proposition? It is still unknown whether there are infinite perfect numbers or not. But till now, we know only 51 perfect numbers. The first 10 perfect numbers are:. No, 9 is not a perfect number as the factors of 9 excluding it are 1 and 3 which is not added to 9.

There are around 51 known perfect numbers. The most naive technique is to test all divisors strictly smaller to the number of which we want to determine the primality here First, we can eliminate all even numbers greater than 2 and hence 4 , 6 , 8 …. Then, we can stop this check when we reach the square root of the number of which we want to determine the primality here the square root is about Historically, the sieve of Eratosthenes dating from the Greek mathematics implements this technique in a relatively efficient manner.

More modern techniques include the sieve of Atkin, probabilistic algorithms, and the cyclotomic AKS test. Is this number a prime number? For , the answer is: No, is not a prime number.
