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.

Is the number 18 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
Is 20 an abundant number?
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. :)
What is a number where its factors add up to itself called?
It is called a perfect number.
Is 50 a perfect abundant or deficient?
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.
If you add a prime number to itself is the sum composite or prime?
Composite.
