Question

N is the set of real numbers that are factors of 12

{1, 2, 3, 4, 6}
    {1, 2, 3, 4, 6, 12}
    {1, 2, 3, 4, 5, 6, 8, 12}
    {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

really, ok 2 x 6=12
3 x4 =12 
so we have from what you have listed 
( 1,2,3,4,6,12)
but really it should only be 2,3,4,6 and thats it

First, this isn't a question.  Second, every real number is a factor of 12.  Third, if you meant the set of positive integers or the set of whole numbers or the set of natural numbers that are factors of 12, just list all the numbers from 1 to 12, try dividing 12 by each one, and see which ones divide evenly.

Contrary to what Elassiam said, 1 and 12 are both factors of 12.  Every number is divisible at least by 1 and itself.

Sorry.  Every real number except 0.
