How do I find the factors or divisors of the number 398,220?

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 398,220, 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.

1 398,220

Next, we take the number 398,220 and divide it by 2.

In this case, 398,220 ÷ 2 = 199,110

If the quotient is a whole number, then 2 and 199,110 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 199,110 398,220

Now, we try dividing 398,220 by 3.

398,220 ÷ 3 = 132,740

If the quotient is a whole number, then 3 and 132,740 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 3 132,740 199,110 398,220

Let's try dividing by 4.

398,220 ÷ 4 = 99,555

If the quotient is a whole number, then 4 and 99,555 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 99,555 132,740 199,110 398,220

We keep dividing by the next largest number, in this case the number 5. If the quotient of 398,220 ÷ 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:

1234561012152030606,63713,27419,91126,54833,18539,82266,37079,64499,555132,740199,110398,220

All of the numbers in the table above can be evenly divided into the number 398,220.

Finally, for your reference, here are all of the divisor combinations of the number 398,220:
