How do I find the factor combinations of the number 24,870,084?

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 24,870,084, 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 24,870,084
-1 -24,870,084

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 24,870,084.

Example:
1 x 24,870,084 = 24,870,084
and
-1 x -24,870,084 = 24,870,084
Notice both answers equal 24,870,084

With that explanation out of the way, let's continue. Next, we take the number 24,870,084 and divide it by 2:

24,870,084 ÷ 2 = 12,435,042

If the quotient is a whole number, then 2 and 12,435,042 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 12,435,042 24,870,084
-1 -2 -12,435,042 -24,870,084

Now, we try dividing 24,870,084 by 3:

24,870,084 ÷ 3 = 8,290,028

If the quotient is a whole number, then 3 and 8,290,028 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 8,290,028 12,435,042 24,870,084
-1 -2 -3 -8,290,028 -12,435,042 -24,870,084

Let's try dividing by 4:

24,870,084 ÷ 4 = 6,217,521

If the quotient is a whole number, then 4 and 6,217,521 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 6,217,521 8,290,028 12,435,042 24,870,084
-1 -2 -3 -4 -6,217,521 -8,290,028 -12,435,042 24,870,084
Keep dividing by the next highest number until you cannot divide anymore.

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

1234612234669921382512763595027187531,0041,0771,4361,5062,1543,0124,3085,7738,25711,54616,51417,31923,09224,77133,02834,63849,54269,27690,10999,084180,218270,327360,436540,6541,081,3082,072,5074,145,0146,217,5218,290,02812,435,04224,870,084
