How do I find the factors or divisors of the number 31,184,280?

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 31,184,280, 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 31,184,280

Next, we take the number 31,184,280 and divide it by 2.

In this case, 31,184,280 ÷ 2 = 15,592,140

If the quotient is a whole number, then 2 and 15,592,140 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 15,592,140 31,184,280

Now, we try dividing 31,184,280 by 3.

31,184,280 ÷ 3 = 10,394,760

If the quotient is a whole number, then 3 and 10,394,760 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 10,394,760 15,592,140 31,184,280

Let's try dividing by 4.

31,184,280 ÷ 4 = 7,796,070

If the quotient is a whole number, then 4 and 7,796,070 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 7,796,070 10,394,760 15,592,140 31,184,280

We keep dividing by the next largest number, in this case the number 5. If the quotient of 31,184,280 ÷ 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:
