How do I find the factors or divisors of the number 423,321,002?

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 423,321,002, 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.

1 423,321,002

Next, we take the number 423,321,002 and divide it by 2.

In this case, 423,321,002 ÷ 2 = 211,660,501

If the quotient is a whole number, then 2 and 211,660,501 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 211,660,501 423,321,002

Now, we try dividing 423,321,002 by 3.

423,321,002 ÷ 3 = 141,107,000.6667

If the quotient is a whole number, then 3 and 141,107,000.6667 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 2 211,660,501 423,321,002

Let's try dividing by 4.

423,321,002 ÷ 4 = 105,830,250.5

If the quotient is a whole number, then 4 and 105,830,250.5 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 2 211,660,501 423,321,002

We keep dividing by the next largest number, in this case the number 5. If the quotient of 423,321,002 ÷ 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:

1213261693381,252,4292,504,85816,281,57732,563,154211,660,501423,321,002

All of the numbers in the table above can be evenly divided into the number 423,321,002.
