How do I find the factors or divisors of the number 231,223,220?

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 231,223,220, 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.

1 231,223,220

Next, we take the number 231,223,220 and divide it by 2.

In this case, 231,223,220 ÷ 2 = 115,611,610

If the quotient is a whole number, then 2 and 115,611,610 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 115,611,610 231,223,220

Now, we try dividing 231,223,220 by 3.

231,223,220 ÷ 3 = 77,074,406.6667

If the quotient is a whole number, then 3 and 77,074,406.6667 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 2 115,611,610 231,223,220

Let's try dividing by 4.

231,223,220 ÷ 4 = 57,805,805

If the quotient is a whole number, then 4 and 57,805,805 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 57,805,805 115,611,610 231,223,220

We keep dividing by the next largest number, in this case the number 5. If the quotient of 231,223,220 ÷ 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:

1245102011,561,16123,122,32246,244,64457,805,805115,611,610231,223,220

All of the numbers in the table above can be evenly divided into the number 231,223,220.
