How do I find the factors or divisors of the number 81,564?

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 81,564, 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 81,564

Next, we take the number 81,564 and divide it by 2.

In this case, 81,564 ÷ 2 = 40,782

If the quotient is a whole number, then 2 and 40,782 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 40,782 81,564

Now, we try dividing 81,564 by 3.

81,564 ÷ 3 = 27,188

If the quotient is a whole number, then 3 and 27,188 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 27,188 40,782 81,564

Let's try dividing by 4.

81,564 ÷ 4 = 20,391

If the quotient is a whole number, then 4 and 20,391 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 20,391 27,188 40,782 81,564

We keep dividing by the next largest number, in this case the number 5. If the quotient of 81,564 ÷ 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:

1234671214212842849711,9422,9133,8845,8266,79711,65213,59420,39127,18840,78281,564

All of the numbers in the table above can be evenly divided into the number 81,564.

Finally, for your reference, here are all of the divisor combinations of the number 81,564:

1 x 815642 x 407823 x 271884 x 203916 x 135947 x 1165212 x 679714 x 582621 x 388428 x 291342 x 194284 x 971
