How do I find the factors or divisors of the number 720,073,156?

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 720,073,156, 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.

1 720,073,156

Next, we take the number 720,073,156 and divide it by 2.

In this case, 720,073,156 ÷ 2 = 360,036,578

If the quotient is a whole number, then 2 and 360,036,578 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 360,036,578 720,073,156

Now, we try dividing 720,073,156 by 3.

720,073,156 ÷ 3 = 240,024,385.3333

If the quotient is a whole number, then 3 and 240,024,385.3333 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 2 360,036,578 720,073,156

Let's try dividing by 4.

720,073,156 ÷ 4 = 180,018,289

If the quotient is a whole number, then 4 and 180,018,289 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 4 180,018,289 360,036,578 720,073,156

We keep dividing by the next largest number, in this case the number 5. If the quotient of 720,073,156 ÷ 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:

12411224416,365,29932,730,59865,461,196180,018,289360,036,578720,073,156

All of the numbers in the table above can be evenly divided into the number 720,073,156.
