How do I find the factors or divisors of the number 689,240?

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 689,240, 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.

1 689,240

Next, we take the number 689,240 and divide it by 2.

In this case, 689,240 ÷ 2 = 344,620

If the quotient is a whole number, then 2 and 344,620 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 344,620 689,240

Now, we try dividing 689,240 by 3.

689,240 ÷ 3 = 229,746.6667

If the quotient is a whole number, then 3 and 229,746.6667 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 2 344,620 689,240

Let's try dividing by 4.

689,240 ÷ 4 = 172,310

If the quotient is a whole number, then 4 and 172,310 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 4 172,310 344,620 689,240

We keep dividing by the next largest number, in this case the number 5. If the quotient of 689,240 ÷ 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:

1245810204017,23134,46268,92486,155137,848172,310344,620689,240

All of the numbers in the table above can be evenly divided into the number 689,240.
