2,14,4,7,1,28

Explanation:

Find biggest and smallest factor
Your biggest factor is the number itself, $28$ $28$ . With the biggest number, you also have the smallest factor, $1$ $1$ .

For the rest of the factors;
Divide the number by $2$ $2$ . $\frac{28}{2} = 14$ $28/2=14$ . Hence you should be looking for factors no bigger than $14$ $14$ .

You already have $14$ $14$ and $2$ $2$ .

Find factors of smaller factors
What is a factor of $14$ $14$ ?

$7$ $7$ !

If $7$ $7$ is a factor of $14$ $14$ , it should be a factor of $28$ $28$ . If so, what times $7$ $7$ becomes $28$ $28$ ?

4!

Every factor has its pair
If you've found a factor, ie: 2, It should have its pair. Just divide the number by 2.
If a factor is 7, divide 28 by 7 and you get 4.
