You cannot make a number abundant. Being abundant is an inherent property of a number that cannot be changed. To work out if a number is abundant, you take all of its factors (apart from itself) and add them up. If the total is less than the original number it is deficient. If it is equal then it is perfect. If the total is greater than the original number, then it is abundant.
An Abundant Number is one that the factors (other than itself) add up to more than the number. 18 factors into [2 3 3] so the factor list is {1 2 3 6 9 18} and the sum of the rest is 21. Since 21 is greater than 18, it is an abundant number.Yes 18 is an abundant number because if you add all of it's factors (1,2,3,6,9,) together the sum is 21.Definition of Abundant- a number that is less the sum of it's factors or integers
Yes 20 is an ABUNDANT number because 1+2+4+5+10=22 and that is more than 20. PS how to find and ABUNDANT number is to add up all its factors. :)
It is called a perfect number.
Just use the basic definition of "abundant" and "deficient". That is, calculate all the factors of 50 (excluding 50 itself), add them up, then compare whether the result is more or less than 50.
Add together all the factors of a number, apart from itself. If the answer is less than the number, then it is deficient. If the answer is equal to the number, then it is perfect. If the answer is greater than the number, then it is abundant. The factors of 8 are 1, 2 and 4. 1+2+4 = 7 so 8 is deficient. The factors of 6 are 1, 2 and 3. 1+2+3 = 6 so 6 is perfect. The factors of 12 are 1, 2, 3, 4 and 6. 1+2+3+4+6 = 16 so 12 is abundant.
All prime numbers are going to be deficient, because remember that a prime number's only factors are one and itself. To find if its deficient or abundant, you'd add up all of its factors, excluding itself. If its only other factor beside itself is one, that's obviously less than the number, and therefore it will be deficient.

An abundant number means its proper factors add up to more than that number.

Cubes of numbers are made by multiplying a number by itself three times.
First of all, to know if a number is abundant, deficient, or perfect, you need to know all the factors of your given number. The factors of 28 are 1,2,4,7,14, and 28. Add your proper factors -or the factors except itself- and determine if the sum of the proper factors is below (deficient), above (abundant), or the exact same amount (perfect). In this case, if you add the proper factors, it equals exactly 28. Because it is exact, it is perfect! =)
Prime number
A perfect number is a number with factors (excluding itself) that add up to the original number. An abundant number is where this sum is greater than the original number. A deficient number is where the sum is less than the original number. In the case of 24, the factors are 1, 2, 3, 4, 6, 8, 12 and 24. Summing the factors (apart from 24) gives us 1+2+3+4+6+8+12 which equals 36. This is greater than 24, the original number, and so 24 is an abundant number.
doubling
It is called a perfect number.
When you add a number to itself, you are multiplying it by 2. The usual term for this is you are doubling the number.
you times 8 by half (1/2) to get 4 NO. There is another whole number that you can add to itself to get the number 8.
