How do I find the factors or divisors of the number 717,321,156?

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 717,321,156, 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.

1 717,321,156

Next, we take the number 717,321,156 and divide it by 2.

In this case, 717,321,156 ÷ 2 = 358,660,578

If the quotient is a whole number, then 2 and 358,660,578 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 358,660,578 717,321,156

Now, we try dividing 717,321,156 by 3.

717,321,156 ÷ 3 = 239,107,052

If the quotient is a whole number, then 3 and 239,107,052 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 3 239,107,052 358,660,578 717,321,156

Let's try dividing by 4.

717,321,156 ÷ 4 = 179,330,289

If the quotient is a whole number, then 4 and 179,330,289 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 4 179,330,289 239,107,052 358,660,578 717,321,156

We keep dividing by the next largest number, in this case the number 5. If the quotient of 717,321,156 ÷ 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:
