How do I find the factors or divisors of the number 688,720?

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 688,720, 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.

1 688,720

Next, we take the number 688,720 and divide it by 2.

In this case, 688,720 ÷ 2 = 344,360

If the quotient is a whole number, then 2 and 344,360 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 344,360 688,720

Now, we try dividing 688,720 by 3.

688,720 ÷ 3 = 229,573.3333

If the quotient is a whole number, then 3 and 229,573.3333 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 2 344,360 688,720

Let's try dividing by 4.

688,720 ÷ 4 = 172,180

If the quotient is a whole number, then 4 and 172,180 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 4 172,180 344,360 688,720

We keep dividing by the next largest number, in this case the number 5. If the quotient of 688,720 ÷ 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:

1245810162040808,60917,21834,43643,04568,87286,090137,744172,180344,360688,720

All of the numbers in the table above can be evenly divided into the number 688,720.

Finally, for your reference, here are all of the divisor combinations of the number 688,720:

1 x 6887202 x 3443604 x 1721805 x 1377448 x 8609010 x 6887216 x 4304520 x 3443640 x 1721880 x 8609
