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 321,223,313, 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 | 321,223,313 | |
| -1 | -321,223,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,223,313.
Example:
1 x 321,223,313 = 321,223,313
and
-1 x -321,223,313 = 321,223,313
Notice both answers equal 321,223,313
With that explanation out of the way, let's continue. Next, we take the number 321,223,313 and divide it by 2:
321,223,313 ÷ 2 = 160,611,656.5
If the quotient is a whole number, then 2 and 160,611,656.5 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 | 321,223,313 | |
| -1 | -321,223,313 |
Now, we try dividing 321,223,313 by 3:
321,223,313 ÷ 3 = 107,074,437.6667
If the quotient is a whole number, then 3 and 107,074,437.6667 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 | 321,223,313 | |
| -1 | -321,223,313 |
Let's try dividing by 4:
321,223,313 ÷ 4 = 80,305,828.25
If the quotient is a whole number, then 4 and 80,305,828.25 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 | 321,223,313 | |
| -1 | 321,223,313 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 391 | 811 | 1,013 | 13,787 | 17,221 | 18,653 | 23,299 | 317,101 | 396,083 | 821,543 | 13,966,231 | 18,895,489 | 321,223,313 |
| -1 | -17 | -23 | -391 | -811 | -1,013 | -13,787 | -17,221 | -18,653 | -23,299 | -317,101 | -396,083 | -821,543 | -13,966,231 | -18,895,489 | -321,223,313 |
