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 12,332,021, 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 | 12,332,021 | |
| -1 | -12,332,021 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,332,021.
Example:
1 x 12,332,021 = 12,332,021
and
-1 x -12,332,021 = 12,332,021
Notice both answers equal 12,332,021
With that explanation out of the way, let's continue. Next, we take the number 12,332,021 and divide it by 2:
12,332,021 ÷ 2 = 6,166,010.5
If the quotient is a whole number, then 2 and 6,166,010.5 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 | 12,332,021 | |
| -1 | -12,332,021 |
Now, we try dividing 12,332,021 by 3:
12,332,021 ÷ 3 = 4,110,673.6667
If the quotient is a whole number, then 3 and 4,110,673.6667 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 | 12,332,021 | |
| -1 | -12,332,021 |
Let's try dividing by 4:
12,332,021 ÷ 4 = 3,083,005.25
If the quotient is a whole number, then 4 and 3,083,005.25 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 | 12,332,021 | |
| -1 | 12,332,021 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 41 | 221 | 533 | 697 | 1,361 | 9,061 | 17,693 | 23,137 | 55,801 | 300,781 | 725,413 | 948,617 | 12,332,021 |
| -1 | -13 | -17 | -41 | -221 | -533 | -697 | -1,361 | -9,061 | -17,693 | -23,137 | -55,801 | -300,781 | -725,413 | -948,617 | -12,332,021 |
