should i take then away the 1, and 16 from the question of the listing all the factors of 16. so i should leave it as:

list all the factors of 16: 2,4,8

I would leave out 1 and 16, since the pair is obvious and does not divide up the number 16 into smaller integers. I can't read the mind of your teacher however.

To list all the factors of a number, including 16, you need to consider all the integers that divide evenly into it. This means that the factors of 16 are the integers that, when multiplied together, give you the number 16.

In the case of 16, the factors would be 1, 2, 4, 8, and 16. The number 1 is always a factor of any number, and the number itself (in this case, 16) is also a factor. So, you should include 1 and 16 in the list.

Therefore, the correct way to list all the factors of 16 would be:
Factors of 16: 1, 2, 4, 8, 16

Including all the factors provides a comprehensive list that covers all possible divisors of 16.
