How do I find the factors or divisors of the number 31,420,028?

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 31,420,028, 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 31,420,028

Next, we take the number 31,420,028 and divide it by 2.

In this case, 31,420,028 ÷ 2 = 15,710,014

If the quotient is a whole number, then 2 and 15,710,014 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 15,710,014 31,420,028

Now, we try dividing 31,420,028 by 3.

31,420,028 ÷ 3 = 10,473,342.6667

If the quotient is a whole number, then 3 and 10,473,342.6667 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 15,710,014 31,420,028

Let's try dividing by 4.

31,420,028 ÷ 4 = 7,855,007

If the quotient is a whole number, then 4 and 7,855,007 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 4 7,855,007 15,710,014 31,420,028

We keep dividing by the next largest number, in this case the number 5. If the quotient of 31,420,028 ÷ 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:

1243737461,49221,05942,11884,2367,855,00715,710,01431,420,028

All of the numbers in the table above can be evenly divided into the number 31,420,028.
