How do I find the factors or divisors of the number 727,673,820?

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 727,673,820, 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.

1 727,673,820

Next, we take the number 727,673,820 and divide it by 2.

In this case, 727,673,820 ÷ 2 = 363,836,910

If the quotient is a whole number, then 2 and 363,836,910 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 363,836,910 727,673,820

Now, we try dividing 727,673,820 by 3.

727,673,820 ÷ 3 = 242,557,940

If the quotient is a whole number, then 3 and 242,557,940 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 3 242,557,940 363,836,910 727,673,820

Let's try dividing by 4.

727,673,820 ÷ 4 = 181,918,455

If the quotient is a whole number, then 4 and 181,918,455 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 4 181,918,455 242,557,940 363,836,910 727,673,820

We keep dividing by the next largest number, in this case the number 5. If the quotient of 727,673,820 ÷ 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:
