How do I find the factor combinations of the number 89,643,900?

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 89,643,900, 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 89,643,900
-1 -89,643,900

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 89,643,900.

Example:
1 x 89,643,900 = 89,643,900
and
-1 x -89,643,900 = 89,643,900
Notice both answers equal 89,643,900

With that explanation out of the way, let's continue. Next, we take the number 89,643,900 and divide it by 2:

89,643,900 ÷ 2 = 44,821,950

If the quotient is a whole number, then 2 and 44,821,950 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 44,821,950 89,643,900
-1 -2 -44,821,950 -89,643,900

Now, we try dividing 89,643,900 by 3:

89,643,900 ÷ 3 = 29,881,300

If the quotient is a whole number, then 3 and 29,881,300 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 29,881,300 44,821,950 89,643,900
-1 -2 -3 -29,881,300 -44,821,950 -89,643,900

Let's try dividing by 4:

89,643,900 ÷ 4 = 22,410,975

If the quotient is a whole number, then 4 and 22,410,975 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 22,410,975 29,881,300 44,821,950 89,643,900
-1 -2 -3 -4 -22,410,975 -29,881,300 -44,821,950 89,643,900
Keep dividing by the next highest number until you cannot divide anymore.

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