Best Answer

Perfect numbers have the form 2n-1(2n-1) where 2n-1 is a Mersenne prime. When a new Mersenne prime is discovered, so is a new perfect number.

There is a one-to-one relationship between even perfect numbers and Mersenne primes. It is unknown whether there are any odd perfect numbers.

A Mersenne prime has the form 2n-1. For 2n-1 to be prime, n must also be prime. Perfect numbers have the form 2n-1(2n-1) where 2n-1 is a Mersenne prime, so when a new Mersenne prime is discovered, another perfect number is also found.

Mersenne primes are mostly of interest as mathematical curios. A Mersenne prime has the form 2n-1. For 2n-1 to be prime, n must also be prime. Perfect numbers have the form 2n-1(2n-1) where 2n-1 is a Mersenne prime, so when a new Mersenne prime is discovered, another perfect number is also found.

So far 47. Euler proved that every even perfect number will be of the form 2p−1(2p−1), where p is prime and 2p−1 is also prime. If 2p−1 is prime it is known as a Mersenne prime. Since 47 Mersenne primes are known, 47 even perfect numbers are known. As for odd perfect numbers, none are known, nor has it been proven yet that there aren't any.

No, there are no known perfect numbers between 1 and 30. The only perfect numbers that have been discovered are 6, 28, 496, and 8128.

It would be extremely large, if it exists.Briefly:It is known that all perfect (even) numbers are generated by the formula 2pâˆ’1(2pâˆ’1) whenever 2pâˆ’1 is prime.When 2pâˆ’1 is prime, it is known as a Mersenne prime. There are currently (as of October 2009) only 47 known Mersenne primes, the largest of which has almost 13 million digits.It is unknown if there are further Mersenne primes between the 40th one and the current 47th one.It is unknown if there are infinitely many Mersenne Primes.It is also unknown if there are any odd perfect numbers, but the evidence so far is that the first one to exist must be extremely large.So there may, or may not, be a 100th perfect number.There are only 47 known perfect (even) numbers - one for each of the 47 Mersenne primes.

The square roots of perfect squares are the numbers that when squared create perfect squares as for example 36 is a perfect square and its square root is 6 which when squared is 36

The two perfect numbers between 1 and 30 are: 6, 28

There are no perfect numbers between 20 and 30. Perfect numbers are numbers that are equal to the sum of their proper divisors, excluding the number itself. The perfect numbers within this range would be 28, but that is incorrect as 28 is not a perfect number.

No, there are no known perfect numbers between 1 and 30. The only perfect numbers that have been discovered are 6, 28, 496, and 8128.

There are 31 perfect square numbers between 1 and 1000 (including 1).

There is a formula, which uses Mersenne primes. If you don't know what that is, then you'll find it somewhere on the internet. The formula is this: 2n-1 x (2n-1) This will only work if the bit inside the bracket is a Mersenne prime. =)

There are 24 perfect squares between 50 and 1000.
