How do I find the factors or divisors of the number 720,722,511?

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 720,722,511, 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.

1 720,722,511

Next, we take the number 720,722,511 and divide it by 2.

In this case, 720,722,511 ÷ 2 = 360,361,255.5

If the quotient is a whole number, then 2 and 360,361,255.5 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 720,722,511

Now, we try dividing 720,722,511 by 3.

720,722,511 ÷ 3 = 240,240,837

If the quotient is a whole number, then 3 and 240,240,837 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 3 240,240,837 720,722,511

Let's try dividing by 4.

720,722,511 ÷ 4 = 180,180,627.75

If the quotient is a whole number, then 4 and 180,180,627.75 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 3 240,240,837 720,722,511

We keep dividing by the next largest number, in this case the number 5. If the quotient of 720,722,511 ÷ 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:

1396,31112,68918,93338,06756,799114,20180,080,279240,240,837720,722,511

All of the numbers in the table above can be evenly divided into the number 720,722,511.
