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 323,111,129, 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 | 323,111,129 | |
| -1 | -323,111,129 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,111,129.
Example:
1 x 323,111,129 = 323,111,129
and
-1 x -323,111,129 = 323,111,129
Notice both answers equal 323,111,129
With that explanation out of the way, let's continue. Next, we take the number 323,111,129 and divide it by 2:
323,111,129 ÷ 2 = 161,555,564.5
If the quotient is a whole number, then 2 and 161,555,564.5 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 | 323,111,129 | |
| -1 | -323,111,129 |
Now, we try dividing 323,111,129 by 3:
323,111,129 ÷ 3 = 107,703,709.6667
If the quotient is a whole number, then 3 and 107,703,709.6667 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 | 323,111,129 | |
| -1 | -323,111,129 |
Let's try dividing by 4:
323,111,129 ÷ 4 = 80,777,782.25
If the quotient is a whole number, then 4 and 80,777,782.25 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 | 323,111,129 | |
| -1 | 323,111,129 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 359 | 3,949 | 4,813 | 6,103 | 52,943 | 67,133 | 81,821 | 900,031 | 1,727,867 | 19,006,537 | 29,373,739 | 323,111,129 |
| -1 | -11 | -17 | -187 | -359 | -3,949 | -4,813 | -6,103 | -52,943 | -67,133 | -81,821 | -900,031 | -1,727,867 | -19,006,537 | -29,373,739 | -323,111,129 |
