How do I find the factors or divisors of the number 139,230,720?

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 139,230,720, 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.

1 139,230,720

Next, we take the number 139,230,720 and divide it by 2.

In this case, 139,230,720 ÷ 2 = 69,615,360

If the quotient is a whole number, then 2 and 69,615,360 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 69,615,360 139,230,720

Now, we try dividing 139,230,720 by 3.

139,230,720 ÷ 3 = 46,410,240

If the quotient is a whole number, then 3 and 46,410,240 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 46,410,240 69,615,360 139,230,720

Let's try dividing by 4.

139,230,720 ÷ 4 = 34,807,680

If the quotient is a whole number, then 4 and 34,807,680 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 34,807,680 46,410,240 69,615,360 139,230,720

We keep dividing by the next largest number, in this case the number 5. If the quotient of 139,230,720 ÷ 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:
