When you know the answer and one of the factors in a multiplication problem, you can use division to find the third number.
So, in your question you know that 4 times a number equals 5616.
To find this number, we can just divide 5616 by 4.
5616 / 4 = 1404
Therefore, 4 times 1404 equals 5616.
Hope this helps! :)
