How do I find the factors or divisors of the number 31,533,516?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 31,533,516, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1 31,533,516

Next, we take the number 31,533,516 and divide it by 2.

In this case, 31,533,516 ÷ 2 = 15,766,758

If the quotient is a whole number, then 2 and 15,766,758 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 15,766,758 31,533,516

Now, we try dividing 31,533,516 by 3.

31,533,516 ÷ 3 = 10,511,172

If the quotient is a whole number, then 3 and 10,511,172 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 10,511,172 15,766,758 31,533,516

Let's try dividing by 4.

31,533,516 ÷ 4 = 7,883,379

If the quotient is a whole number, then 4 and 7,883,379 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 3 4 7,883,379 10,511,172 15,766,758 31,533,516

We keep dividing by the next largest number, in this case the number 5. If the quotient of 31,533,516 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:
