How do I find the factor combinations of the number 303,616,405?

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 303,616,405, 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.

1 303,616,405
-1 -303,616,405

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 303,616,405.

Example:
1 x 303,616,405 = 303,616,405
and
-1 x -303,616,405 = 303,616,405
Notice both answers equal 303,616,405

With that explanation out of the way, let's continue. Next, we take the number 303,616,405 and divide it by 2:

303,616,405 ÷ 2 = 151,808,202.5

If the quotient is a whole number, then 2 and 151,808,202.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 303,616,405
-1 -303,616,405

Now, we try dividing 303,616,405 by 3:

303,616,405 ÷ 3 = 101,205,468.3333

If the quotient is a whole number, then 3 and 101,205,468.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 303,616,405
-1 -303,616,405

Let's try dividing by 4:

303,616,405 ÷ 4 = 75,904,101.25

If the quotient is a whole number, then 4 and 75,904,101.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 303,616,405
-1 303,616,405
Keep dividing by the next highest number until you cannot divide anymore.

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

152633736191,3151,8653,09598,099162,797230,887490,495813,9851,154,43560,723,281303,616,405
