How do I find the factor combinations of the number 17,136,013?

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 17,136,013, 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 17,136,013
-1 -17,136,013

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 17,136,013.

Example:
1 x 17,136,013 = 17,136,013
and
-1 x -17,136,013 = 17,136,013
Notice both answers equal 17,136,013

With that explanation out of the way, let's continue. Next, we take the number 17,136,013 and divide it by 2:

17,136,013 ÷ 2 = 8,568,006.5

If the quotient is a whole number, then 2 and 8,568,006.5 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 17,136,013
-1 -17,136,013

Now, we try dividing 17,136,013 by 3:

17,136,013 ÷ 3 = 5,712,004.3333

If the quotient is a whole number, then 3 and 5,712,004.3333 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 17,136,013
-1 -17,136,013

Let's try dividing by 4:

17,136,013 ÷ 4 = 4,284,003.25

If the quotient is a whole number, then 4 and 4,284,003.25 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 17,136,013
-1 17,136,013
Keep dividing by the next highest number until you cannot divide anymore.

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

129531,53711,149323,321590,89717,136,013
