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 326,881,373, 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 | 326,881,373 | |
| -1 | -326,881,373 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 326,881,373.
Example:
1 x 326,881,373 = 326,881,373
and
-1 x -326,881,373 = 326,881,373
Notice both answers equal 326,881,373
With that explanation out of the way, let's continue. Next, we take the number 326,881,373 and divide it by 2:
326,881,373 ÷ 2 = 163,440,686.5
If the quotient is a whole number, then 2 and 163,440,686.5 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 | 326,881,373 | |
| -1 | -326,881,373 |
Now, we try dividing 326,881,373 by 3:
326,881,373 ÷ 3 = 108,960,457.6667
If the quotient is a whole number, then 3 and 108,960,457.6667 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 | 326,881,373 | |
| -1 | -326,881,373 |
Let's try dividing by 4:
326,881,373 ÷ 4 = 81,720,343.25
If the quotient is a whole number, then 4 and 81,720,343.25 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 | 326,881,373 | |
| -1 | 326,881,373 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 71 | 91 | 497 | 923 | 6,461 | 50,593 | 354,151 | 657,709 | 3,592,103 | 4,603,963 | 25,144,721 | 46,697,339 | 326,881,373 |
| -1 | -7 | -13 | -71 | -91 | -497 | -923 | -6,461 | -50,593 | -354,151 | -657,709 | -3,592,103 | -4,603,963 | -25,144,721 | -46,697,339 | -326,881,373 |
