A perfect number is equal to the sum of its proper divisors (the factors excluding the number itself.)
6 is a perfect number. Its proper divisors are 1, 2 and 3.
an example of a near perfect number is 2, 4 or 16.-these are near-perfect numbers because their factors add up to one less than the number itself.
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.
no, but I don't know why. One is not a prime number and by definition of a perfect number one must be a prime number.
No, a perfect square is the square of an integer number. Fractions are never a perfect square, as the square of an integer is always another integer.Actually fractions can be perfect squares an example is one ninth, it would be one third times one third which equals one ninth.
1/4 (one-fourth)
One is deficent
A near-perfect number is one that is close to being a perfect one (obvi). So to find out if it's perfect or not (there are other terms, but that doesn't really matter right now), you add up it's divisors other than itself. So for example: 6 is a perfect number because 1+2+3+6. 16 1+2+4+8=15, so thus it is near-perfect. The four perfect numbers are 6, 28, 496, 8128
The Earth is not a perfect sphere. The diameter varies depending on where you measure it.
Why would some one even do that. OK 1234567891011 there
A perfect number is one with factors (apart from itself) that sum to give the original number. An abundant number is one where this sum is greater than the original number. A deficient number is one where the sum is less than the original number. The factors of 75 are 1, 3, 5, 15 and 25. The sum of these numbers is 49. Thus 75 is a deficient number.
only the number 1 (one)because it is perfect nth root .
It is impossible to have a surd that is not irrational. Surds are defined to be an irrational number (square root of a number).
