How do I find the factors or divisors of the number 3,640,580?

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 3,640,580, 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 3,640,580

Next, we take the number 3,640,580 and divide it by 2.

In this case, 3,640,580 ÷ 2 = 1,820,290

If the quotient is a whole number, then 2 and 1,820,290 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 1,820,290 3,640,580

Now, we try dividing 3,640,580 by 3.

3,640,580 ÷ 3 = 1,213,526.6667

If the quotient is a whole number, then 3 and 1,213,526.6667 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 1,820,290 3,640,580

Let's try dividing by 4.

3,640,580 ÷ 4 = 910,145

If the quotient is a whole number, then 4 and 910,145 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 4 910,145 1,820,290 3,640,580

We keep dividing by the next largest number, in this case the number 5. If the quotient of 3,640,580 ÷ 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:

12451020182,029364,058728,116910,1451,820,2903,640,580

All of the numbers in the table above can be evenly divided into the number 3,640,580.

Finally, for your reference, here are all of the divisor combinations of the number 3,640,580:

1 x 3640580
2 x 1820290
4 x 910145
