How do I find the factors or divisors of the number 855,640,224?

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 855,640,224, 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.

1 855,640,224

Next, we take the number 855,640,224 and divide it by 2.

In this case, 855,640,224 ÷ 2 = 427,820,112

If the quotient is a whole number, then 2 and 427,820,112 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 427,820,112 855,640,224

Now, we try dividing 855,640,224 by 3.

855,640,224 ÷ 3 = 285,213,408

If the quotient is a whole number, then 3 and 285,213,408 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 3 285,213,408 427,820,112 855,640,224

Let's try dividing by 4.

855,640,224 ÷ 4 = 213,910,056

If the quotient is a whole number, then 4 and 213,910,056 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 4 213,910,056 285,213,408 427,820,112 855,640,224

We keep dividing by the next largest number, in this case the number 5. If the quotient of 855,640,224 ÷ 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:
