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 323,032,129, 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 | 323,032,129 | |
| -1 | -323,032,129 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,032,129.
Example:
1 x 323,032,129 = 323,032,129
and
-1 x -323,032,129 = 323,032,129
Notice both answers equal 323,032,129
With that explanation out of the way, let's continue. Next, we take the number 323,032,129 and divide it by 2:
323,032,129 ÷ 2 = 161,516,064.5
If the quotient is a whole number, then 2 and 161,516,064.5 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 | 323,032,129 | |
| -1 | -323,032,129 |
Now, we try dividing 323,032,129 by 3:
323,032,129 ÷ 3 = 107,677,376.3333
If the quotient is a whole number, then 3 and 107,677,376.3333 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 | 323,032,129 | |
| -1 | -323,032,129 |
Let's try dividing by 4:
323,032,129 ÷ 4 = 80,758,032.25
If the quotient is a whole number, then 4 and 80,758,032.25 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 | 323,032,129 | |
| -1 | 323,032,129 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 197 | 1,379 | 3,743 | 12,329 | 26,201 | 86,303 | 234,251 | 1,639,757 | 2,428,813 | 17,001,691 | 46,147,447 | 323,032,129 |
| -1 | -7 | -19 | -133 | -197 | -1,379 | -3,743 | -12,329 | -26,201 | -86,303 | -234,251 | -1,639,757 | -2,428,813 | -17,001,691 | -46,147,447 | -323,032,129 |
