Final answer:
After finding factors 1 and 16, 2 and 8, and 4 and 4, the best thing to do next is to check if there are any more factors that can be found. In this case, the factors have been exhausted, and the factors of 16 are 1, 2, 4, 8, and 16.
Step-by-step explanation:
After finding the factors 1 and 16, 2 and 8, and 4 and 4 for the number 16, the best thing to do next is to check if there are any more factors that can be found.
In this case, the factors have been exhausted, and there are no more whole numbers to divide 16 by. Therefore, the factors of 16 are 1, 2, 4, 8, and 16.
