How do I find the factors or divisors of the number 221,023,224?

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 221,023,224, 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.

1 221,023,224

Next, we take the number 221,023,224 and divide it by 2.

In this case, 221,023,224 ÷ 2 = 110,511,612

If the quotient is a whole number, then 2 and 110,511,612 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 110,511,612 221,023,224

Now, we try dividing 221,023,224 by 3.

221,023,224 ÷ 3 = 73,674,408

If the quotient is a whole number, then 3 and 73,674,408 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 73,674,408 110,511,612 221,023,224

Let's try dividing by 4.

221,023,224 ÷ 4 = 55,255,806

If the quotient is a whole number, then 4 and 55,255,806 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 55,255,806 73,674,408 110,511,612 221,023,224

We keep dividing by the next largest number, in this case the number 5. If the quotient of 221,023,224 ÷ 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:
