A perfect number is only classified as a perfect number because all of its proper divisors add up to itself. For example, the proper divisors of six are one, two and three. Those numbers added together equal six. Therefore, six is a perfect number.
6 and 28 are perfect numbers.
there are no perfect numbers instead there are perfect cubes, perfect squares, natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers. If you want natural no. they are 21, 22, 23, 24, 25, 26, 27, 28, and 29.
No. The only perfect numbers less than 100 are 6 and 28. All known perfect numbers are even - it is unknown whether there are odd perfect numbers.
81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.81. They are the perfect squares of numbers starting from 5.
6, 28, 496 and 8128 are the first four Perfect numbers.
By definition, ALL perfect squares are whole numbers!
Natural numbers which are the scales of some natural numbers are perfect squares
There are infinitely many perfect numbers so they cannot all be listed.
Other than what? The first perfect numbers are 6 and 28.
No. The first two "perfect numbers" are 6 and 28.
There is no way to determine the amount of perfect numbers there are. The number could be infinite, but this has yet to be proven. It has also yet to be proven if there are any odd perfect numbers.
There is a one-to-one relationship between even perfect numbers and Mersenne primes. It is unknown whether there are any odd perfect numbers.
