What is the sum of the factors in -14?
The sum of the factors of any negative number is zero.
Are there any quasi-perfect numbers?
A "perfect number" is a number that is equal to the sum of its factors (that is, the factors that are less than the number). As far as I know, there is no concept of "quasi-perfect" in number theory.
What is the sum of all the factors of 30?
The sum of the positive whole-number factors of 30 is 72.
If a number that is more than the sum of its factors it's called what?
You're referring to an Abundant Number(unlike a Perfect Number, which is equal to the sum of its factors).
What number between 20 and 30 has a sum of all its proper factors equal to twice the number itself?
There aren't any numbers like that. You might be thinking of 28, which has a sum of all its factors equal to twice itself, making it a perfect number. Proper factors are a different set.
What does Abundant Deficient and perfect mean?
Abundant is a number for which the sum of all its proper factors is greater than the number itself. Deficient is a number for which the sum of all its proper factors is less than the number itself. Perfect is a number for which the sum of all its proper factors is the number itself.
The sum of any number and 0 is the number?

Why is 6 a perfect number?
A perfect number is an integer, the sum of whose integral factors, including 1, but excluding itself, is equal to itself. In other words, when the sum of a number's proper factors equals itself, it is called a perfect number. That means that if you add all of any given number's factors (including 1, but not itself), you get that number. 6 Factors: 1, 2, 3, 6 Sum of factors less than itself: 1 + 2 + 3 = 6 28 Factors: 1, 2, 4, 7, 14, 28 Sum of factors less than itself: 1 + 2 + 4 + 7 + 14 = 28
How can you prove that a perfect number can never be a prime number?
In a perfect number, the sum of all the factors (including the number itself) is twice the number. E.g., the sum of the factors of 6 is 1 + 2 + 3 + 6 = 12 (equal to 2 x 6). Every prime number has two factors: 1, and itself. So, the sum of the factors is only one more than the prime number itself; for any number greater than 1, this can't be twice the number. For example, the prime number 7 has the factors 1 and 7, which add up to 8.
Which composite number from six to twenty is closest in value to the sum of its prime factors?
The sum of the prime factors of 6 is closest in value to the composite number 6.
What number is a factor of 32 and its sum is odd?
1 and 16 are factors of 32 and their sum is 17 which is an odd number
