Hi there!
First of all, let's determine the factors of 16.
Remember, a factor is a number that a number can be evenly divided by.
Example: 5 is a factor of 10, because 10 can be evenly divided by 5.
So, the factors of 16 are:
1, 2, 4, 8, and 16.
Now, there's an infinite amount of numbers that are not factors of 16. Here are some of them:
3, 5,7,9, 10,11, 12, 13, 14, 15...
Hope it helps.
Feel free to ask if you have any doubts.
