How do I find the factors or divisors of the number 258,990?

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 258,990, 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.

1 258,990

Next, we take the number 258,990 and divide it by 2.

In this case, 258,990 ÷ 2 = 129,495

If the quotient is a whole number, then 2 and 129,495 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 129,495 258,990

Now, we try dividing 258,990 by 3.

258,990 ÷ 3 = 86,330

If the quotient is a whole number, then 3 and 86,330 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 86,330 129,495 258,990

Let's try dividing by 4.

258,990 ÷ 4 = 64,747.5

If the quotient is a whole number, then 4 and 64,747.5 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 86,330 129,495 258,990

We keep dividing by the next largest number, in this case the number 5. If the quotient of 258,990 ÷ 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:

1235610153089971781942672914454855345828909701,3351,4552,6702,9108,63317,26625,89943,16551,79886,330129,495258,990

All of the numbers in the table above can be evenly divided into the number 258,990.

Finally, for your reference, here are all of the divisor combinations of the number 258,990:
