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 12,231,605, 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 | 12,231,605 | |
| -1 | -12,231,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,231,605.
Example:
1 x 12,231,605 = 12,231,605
and
-1 x -12,231,605 = 12,231,605
Notice both answers equal 12,231,605
With that explanation out of the way, let's continue. Next, we take the number 12,231,605 and divide it by 2:
12,231,605 ÷ 2 = 6,115,802.5
If the quotient is a whole number, then 2 and 6,115,802.5 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 | 12,231,605 | |
| -1 | -12,231,605 |
Now, we try dividing 12,231,605 by 3:
12,231,605 ÷ 3 = 4,077,201.6667
If the quotient is a whole number, then 3 and 4,077,201.6667 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 | 12,231,605 | |
| -1 | -12,231,605 |
Let's try dividing by 4:
12,231,605 ÷ 4 = 3,057,901.25
If the quotient is a whole number, then 4 and 3,057,901.25 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 | 12,231,605 | |
| -1 | 12,231,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 53 | 101 | 265 | 457 | 505 | 2,285 | 5,353 | 24,221 | 26,765 | 46,157 | 121,105 | 230,785 | 2,446,321 | 12,231,605 |
| -1 | -5 | -53 | -101 | -265 | -457 | -505 | -2,285 | -5,353 | -24,221 | -26,765 | -46,157 | -121,105 | -230,785 | -2,446,321 | -12,231,605 |
