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 12,322,013, 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 | 12,322,013 | |
| -1 | -12,322,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,322,013.
Example:
1 x 12,322,013 = 12,322,013
and
-1 x -12,322,013 = 12,322,013
Notice both answers equal 12,322,013
With that explanation out of the way, let's continue. Next, we take the number 12,322,013 and divide it by 2:
12,322,013 ÷ 2 = 6,161,006.5
If the quotient is a whole number, then 2 and 6,161,006.5 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 | 12,322,013 | |
| -1 | -12,322,013 |
Now, we try dividing 12,322,013 by 3:
12,322,013 ÷ 3 = 4,107,337.6667
If the quotient is a whole number, then 3 and 4,107,337.6667 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 | 12,322,013 | |
| -1 | -12,322,013 |
Let's try dividing by 4:
12,322,013 ÷ 4 = 3,080,503.25
If the quotient is a whole number, then 4 and 3,080,503.25 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 | 12,322,013 | |
| -1 | 12,322,013 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 29 | 107 | 209 | 319 | 361 | 551 | 1,177 | 2,033 | 3,103 | 3,971 | 6,061 | 10,469 | 22,363 | 34,133 | 38,627 | 58,957 | 115,159 | 424,897 | 648,527 | 1,120,183 | 12,322,013 |
| -1 | -11 | -19 | -29 | -107 | -209 | -319 | -361 | -551 | -1,177 | -2,033 | -3,103 | -3,971 | -6,061 | -10,469 | -22,363 | -34,133 | -38,627 | -58,957 | -115,159 | -424,897 | -648,527 | -1,120,183 | -12,322,013 |
