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 8,481,055, it is easier to work with a table - it's called factoring from the outside in.
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 | 8,481,055 | |
| -1 | -8,481,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,481,055.
Example:
1 x 8,481,055 = 8,481,055
and
-1 x -8,481,055 = 8,481,055
Notice both answers equal 8,481,055
With that explanation out of the way, let's continue. Next, we take the number 8,481,055 and divide it by 2:
8,481,055 ÷ 2 = 4,240,527.5
If the quotient is a whole number, then 2 and 4,240,527.5 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 | 8,481,055 | |
| -1 | -8,481,055 |
Now, we try dividing 8,481,055 by 3:
8,481,055 ÷ 3 = 2,827,018.3333
If the quotient is a whole number, then 3 and 2,827,018.3333 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 | 8,481,055 | |
| -1 | -8,481,055 |
Let's try dividing by 4:
8,481,055 ÷ 4 = 2,120,263.75
If the quotient is a whole number, then 4 and 2,120,263.75 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 | 8,481,055 | |
| -1 | 8,481,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 41 | 55 | 205 | 451 | 2,255 | 3,761 | 18,805 | 41,371 | 154,201 | 206,855 | 771,005 | 1,696,211 | 8,481,055 |
| -1 | -5 | -11 | -41 | -55 | -205 | -451 | -2,255 | -3,761 | -18,805 | -41,371 | -154,201 | -206,855 | -771,005 | -1,696,211 | -8,481,055 |
