How do I find the factor combinations of the number 201,430,416?

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 201,430,416, 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.

1 201,430,416
-1 -201,430,416

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 201,430,416.

Example:
1 x 201,430,416 = 201,430,416
and
-1 x -201,430,416 = 201,430,416
Notice both answers equal 201,430,416

With that explanation out of the way, let's continue. Next, we take the number 201,430,416 and divide it by 2:

201,430,416 ÷ 2 = 100,715,208

If the quotient is a whole number, then 2 and 100,715,208 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 2 100,715,208 201,430,416
-1 -2 -100,715,208 -201,430,416

Now, we try dividing 201,430,416 by 3:

201,430,416 ÷ 3 = 67,143,472

If the quotient is a whole number, then 3 and 67,143,472 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 67,143,472 100,715,208 201,430,416
-1 -2 -3 -67,143,472 -100,715,208 -201,430,416

Let's try dividing by 4:

201,430,416 ÷ 4 = 50,357,604

If the quotient is a whole number, then 4 and 50,357,604 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 50,357,604 67,143,472 100,715,208 201,430,416
-1 -2 -3 -4 -50,357,604 -67,143,472 -100,715,208 201,430,416
Keep dividing by the next highest number until you cannot divide anymore.

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