How do I find the factors or divisors of the number 421,356,668?

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 421,356,668, 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.

1 421,356,668

Next, we take the number 421,356,668 and divide it by 2.

In this case, 421,356,668 ÷ 2 = 210,678,334

If the quotient is a whole number, then 2 and 210,678,334 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 210,678,334 421,356,668

Now, we try dividing 421,356,668 by 3.

421,356,668 ÷ 3 = 140,452,222.6667

If the quotient is a whole number, then 3 and 140,452,222.6667 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 2 210,678,334 421,356,668

Let's try dividing by 4.

421,356,668 ÷ 4 = 105,339,167

If the quotient is a whole number, then 4 and 105,339,167 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 4 105,339,167 210,678,334 421,356,668

We keep dividing by the next largest number, in this case the number 5. If the quotient of 421,356,668 ÷ 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:
