How do I find the factors or divisors of the number 505,451,004?

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 505,451,004, 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.

1 505,451,004

Next, we take the number 505,451,004 and divide it by 2.

In this case, 505,451,004 ÷ 2 = 252,725,502

If the quotient is a whole number, then 2 and 252,725,502 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 252,725,502 505,451,004

Now, we try dividing 505,451,004 by 3.

505,451,004 ÷ 3 = 168,483,668

If the quotient is a whole number, then 3 and 168,483,668 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 3 168,483,668 252,725,502 505,451,004

Let's try dividing by 4.

505,451,004 ÷ 4 = 126,362,751

If the quotient is a whole number, then 4 and 126,362,751 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 4 126,362,751 168,483,668 252,725,502 505,451,004

We keep dividing by the next largest number, in this case the number 5. If the quotient of 505,451,004 ÷ 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:

1234612173451681022042,477,7014,955,4027,433,1039,910,80414,866,20629,732,41242,120,91784,241,834126,362,751168,483,668252,725,502505,451,004

All of the numbers in the table above can be evenly divided into the number 505,451,004.
