2, 4, 6, 10, 12, 20, 30, 60 add up to 144.
The sum of the factors of any negative number is zero.
It is only possible to have one even prime factor of any number - as there is only one even prime number, 2. The sum of these is therefore 2.
If you compare 36 to any other even number, they will have at least 1 and 2 in common.
The factors of 49 are 1, 7, and 49. When you add them together you get 57, which is the sum.
All nonzero numbers have factors. Some factors are even numbers, some factors are odd numbers.
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
39 is a composite number whose proper factors add up to 16.
The sum of the factors of any negative number is zero.
The sum of two odd numbers or two even numbers is an even number. The sum of an odd number and an even number is an odd number.
The sum of an odd number and an even number is an odd number.
It doesn't have to be a prime number and an even number. The sum of any two whole numbers is a whole number. Also, the sum of two even numbers is an even number, the sum of two odd numbers is an even number, and the sum of an odd number and an even number is an odd number.
The sum of the positive whole-number factors of 30 is 72.
Two odd numbers always sum to an even number. Always. Two even numbers always sum to an even number, and an odd number and an even number always sum to an odd number.
No, the sum of a prime number and a composite number is not always even.
You're referring to an Abundant Number(unlike a Perfect Number, which is equal to the sum of its factors).
