How do I find the factors or divisors of the number 660,250,320?

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 660,250,320, 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.

1 660,250,320

Next, we take the number 660,250,320 and divide it by 2.

In this case, 660,250,320 ÷ 2 = 330,125,160

If the quotient is a whole number, then 2 and 330,125,160 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 330,125,160 660,250,320

Now, we try dividing 660,250,320 by 3.

660,250,320 ÷ 3 = 220,083,440

If the quotient is a whole number, then 3 and 220,083,440 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 3 220,083,440 330,125,160 660,250,320

Let's try dividing by 4.

660,250,320 ÷ 4 = 165,062,580

If the quotient is a whole number, then 4 and 165,062,580 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 4 165,062,580 220,083,440 330,125,160 660,250,320

We keep dividing by the next largest number, in this case the number 5. If the quotient of 660,250,320 ÷ 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:
