Is the number 18 abundant

Answer 1

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.
