How do I find the factors or divisors of the number 81,648?

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 81,648, 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 81,648

Next, we take the number 81,648 and divide it by 2.

In this case, 81,648 ÷ 2 = 40,824

If the quotient is a whole number, then 2 and 40,824 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 40,824 81,648

Now, we try dividing 81,648 by 3.

81,648 ÷ 3 = 27,216

If the quotient is a whole number, then 3 and 27,216 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 27,216 40,824 81,648

Let's try dividing by 4.

81,648 ÷ 4 = 20,412

If the quotient is a whole number, then 4 and 20,412 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 20,412 27,216 40,824 81,648

We keep dividing by the next largest number, in this case the number 5. If the quotient of 81,648 ÷ 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:
