How do I find the factors or divisors of the number 217,102,080?

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 217,102,080, 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.

1 217,102,080

Next, we take the number 217,102,080 and divide it by 2.

In this case, 217,102,080 ÷ 2 = 108,551,040

If the quotient is a whole number, then 2 and 108,551,040 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 108,551,040 217,102,080

Now, we try dividing 217,102,080 by 3.

217,102,080 ÷ 3 = 72,367,360

If the quotient is a whole number, then 3 and 72,367,360 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 72,367,360 108,551,040 217,102,080

Let's try dividing by 4.

217,102,080 ÷ 4 = 54,275,520

If the quotient is a whole number, then 4 and 54,275,520 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 54,275,520 72,367,360 108,551,040 217,102,080

We keep dividing by the next largest number, in this case the number 5. If the quotient of 217,102,080 ÷ 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:
