How do I find the factor combinations of the number 345,520,476?

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 divisors of larger numbers. To find the factor combinations of the number 345,520,476, it is easier to work with a table - it's called factoring from the outside in.

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. Then, below that, write the numbers as a negative as well.

1 345,520,476
-1 -345,520,476

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 345,520,476.

Example:
1 x 345,520,476 = 345,520,476
and
-1 x -345,520,476 = 345,520,476
Notice both answers equal 345,520,476

With that explanation out of the way, let's continue. Next, we take the number 345,520,476 and divide it by 2:

345,520,476 ÷ 2 = 172,760,238

If the quotient is a whole number, then 2 and 172,760,238 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 172,760,238 345,520,476
-1 -2 -172,760,238 -345,520,476

Now, we try dividing 345,520,476 by 3:

345,520,476 ÷ 3 = 115,173,492

If the quotient is a whole number, then 3 and 115,173,492 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 115,173,492 172,760,238 345,520,476
-1 -2 -3 -115,173,492 -172,760,238 -345,520,476

Let's try dividing by 4:

345,520,476 ÷ 4 = 86,380,119

If the quotient is a whole number, then 4 and 86,380,119 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 86,380,119 115,173,492 172,760,238 345,520,476
-1 -2 -3 -4 -86,380,119 -115,173,492 -172,760,238 345,520,476
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:
