How do I find the factors or divisors of the number 489,648?

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 489,648, 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.

1 489,648

Next, we take the number 489,648 and divide it by 2.

In this case, 489,648 ÷ 2 = 244,824

If the quotient is a whole number, then 2 and 244,824 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 244,824 489,648

Now, we try dividing 489,648 by 3.

489,648 ÷ 3 = 163,216

If the quotient is a whole number, then 3 and 163,216 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 3 163,216 244,824 489,648

Let's try dividing by 4.

489,648 ÷ 4 = 122,412

If the quotient is a whole number, then 4 and 122,412 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 4 122,412 163,216 244,824 489,648

We keep dividing by the next largest number, in this case the number 5. If the quotient of 489,648 ÷ 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:

123468121624481012023034046068081,2121,6162,4244,84810,20120,40230,60340,80461,20681,608122,412163,216244,824489,648

All of the numbers in the table above can be evenly divided into the number 489,648.
