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 329,181,083, 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 | 329,181,083 | |
| -1 | -329,181,083 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 329,181,083.
Example:
1 x 329,181,083 = 329,181,083
and
-1 x -329,181,083 = 329,181,083
Notice both answers equal 329,181,083
With that explanation out of the way, let's continue. Next, we take the number 329,181,083 and divide it by 2:
329,181,083 ÷ 2 = 164,590,541.5
If the quotient is a whole number, then 2 and 164,590,541.5 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 | 329,181,083 | |
| -1 | -329,181,083 |
Now, we try dividing 329,181,083 by 3:
329,181,083 ÷ 3 = 109,727,027.6667
If the quotient is a whole number, then 3 and 109,727,027.6667 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 | 329,181,083 | |
| -1 | -329,181,083 |
Let's try dividing by 4:
329,181,083 ÷ 4 = 82,295,270.75
If the quotient is a whole number, then 4 and 82,295,270.75 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 | 329,181,083 | |
| -1 | 329,181,083 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 77 | 161 | 253 | 1,771 | 185,873 | 1,301,111 | 2,044,603 | 4,275,079 | 14,312,221 | 29,925,553 | 47,025,869 | 329,181,083 |
| -1 | -7 | -11 | -23 | -77 | -161 | -253 | -1,771 | -185,873 | -1,301,111 | -2,044,603 | -4,275,079 | -14,312,221 | -29,925,553 | -47,025,869 | -329,181,083 |
