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

Lets factor.

12 | 2

6 | 2

3 | 3

1

So,

12 = 2. 2. 3

So we can say: 2 and 3 are factors obviously.

We have 2. 2 so, 2. 2 = 4, he's a factor too.

We have 2. 3 so, 2. 3 = 6, he's a factor too.

Every number have 1 and himself as his factor.

So, n is {1, 2, 3, 4, 6, 12}

1,6,3,4,12

Step-by-step explanation:

This is quite simple. Watch as I get it wrong. I probably miss under stood it.
