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 327,206,135, 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 | 327,206,135 | |
| -1 | -327,206,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 327,206,135.
Example:
1 x 327,206,135 = 327,206,135
and
-1 x -327,206,135 = 327,206,135
Notice both answers equal 327,206,135
With that explanation out of the way, let's continue. Next, we take the number 327,206,135 and divide it by 2:
327,206,135 ÷ 2 = 163,603,067.5
If the quotient is a whole number, then 2 and 163,603,067.5 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 | 327,206,135 | |
| -1 | -327,206,135 |
Now, we try dividing 327,206,135 by 3:
327,206,135 ÷ 3 = 109,068,711.6667
If the quotient is a whole number, then 3 and 109,068,711.6667 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 | 327,206,135 | |
| -1 | -327,206,135 |
Let's try dividing by 4:
327,206,135 ÷ 4 = 81,801,533.75
If the quotient is a whole number, then 4 and 81,801,533.75 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 | 327,206,135 | |
| -1 | 327,206,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 61 | 215 | 305 | 409 | 2,045 | 2,623 | 3,721 | 13,115 | 17,587 | 18,605 | 24,949 | 87,935 | 124,745 | 160,003 | 800,015 | 1,072,807 | 1,521,889 | 5,364,035 | 7,609,445 | 65,441,227 | 327,206,135 |
