How do I find the factor combinations of the number 69,436,872?

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 69,436,872, 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 69,436,872
-1 -69,436,872

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 69,436,872.

Example:
1 x 69,436,872 = 69,436,872
and
-1 x -69,436,872 = 69,436,872
Notice both answers equal 69,436,872

With that explanation out of the way, let's continue. Next, we take the number 69,436,872 and divide it by 2:

69,436,872 ÷ 2 = 34,718,436

If the quotient is a whole number, then 2 and 34,718,436 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 34,718,436 69,436,872
-1 -2 -34,718,436 -69,436,872

Now, we try dividing 69,436,872 by 3:

69,436,872 ÷ 3 = 23,145,624

If the quotient is a whole number, then 3 and 23,145,624 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 23,145,624 34,718,436 69,436,872
-1 -2 -3 -23,145,624 -34,718,436 -69,436,872

Let's try dividing by 4:

69,436,872 ÷ 4 = 17,359,218

If the quotient is a whole number, then 4 and 17,359,218 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 17,359,218 23,145,624 34,718,436 69,436,872
-1 -2 -3 -4 -17,359,218 -23,145,624 -34,718,436 69,436,872
Keep dividing by the next highest number until you cannot divide anymore.

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