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 322,331,407, 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 | 322,331,407 | |
| -1 | -322,331,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,331,407.
Example:
1 x 322,331,407 = 322,331,407
and
-1 x -322,331,407 = 322,331,407
Notice both answers equal 322,331,407
With that explanation out of the way, let's continue. Next, we take the number 322,331,407 and divide it by 2:
322,331,407 ÷ 2 = 161,165,703.5
If the quotient is a whole number, then 2 and 161,165,703.5 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 | 322,331,407 | |
| -1 | -322,331,407 |
Now, we try dividing 322,331,407 by 3:
322,331,407 ÷ 3 = 107,443,802.3333
If the quotient is a whole number, then 3 and 107,443,802.3333 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 | 322,331,407 | |
| -1 | -322,331,407 |
Let's try dividing by 4:
322,331,407 ÷ 4 = 80,582,851.75
If the quotient is a whole number, then 4 and 80,582,851.75 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 | 322,331,407 | |
| -1 | 322,331,407 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 211 | 391 | 3,587 | 3,907 | 4,853 | 66,419 | 82,501 | 89,861 | 824,377 | 1,527,637 | 14,014,409 | 18,960,671 | 322,331,407 |
| -1 | -17 | -23 | -211 | -391 | -3,587 | -3,907 | -4,853 | -66,419 | -82,501 | -89,861 | -824,377 | -1,527,637 | -14,014,409 | -18,960,671 | -322,331,407 |
