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 321,133,309, 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 | 321,133,309 | |
| -1 | -321,133,309 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,133,309.
Example:
1 x 321,133,309 = 321,133,309
and
-1 x -321,133,309 = 321,133,309
Notice both answers equal 321,133,309
With that explanation out of the way, let's continue. Next, we take the number 321,133,309 and divide it by 2:
321,133,309 ÷ 2 = 160,566,654.5
If the quotient is a whole number, then 2 and 160,566,654.5 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 | 321,133,309 | |
| -1 | -321,133,309 |
Now, we try dividing 321,133,309 by 3:
321,133,309 ÷ 3 = 107,044,436.3333
If the quotient is a whole number, then 3 and 107,044,436.3333 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 | 321,133,309 | |
| -1 | -321,133,309 |
Let's try dividing by 4:
321,133,309 ÷ 4 = 80,283,327.25
If the quotient is a whole number, then 4 and 80,283,327.25 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 | 321,133,309 | |
| -1 | 321,133,309 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 49 | 163 | 217 | 1,141 | 1,297 | 1,519 | 5,053 | 7,987 | 9,079 | 35,371 | 40,207 | 63,553 | 211,411 | 247,597 | 281,449 | 1,479,877 | 1,970,143 | 6,553,741 | 10,359,139 | 45,876,187 | 321,133,309 |
| -1 | -7 | -31 | -49 | -163 | -217 | -1,141 | -1,297 | -1,519 | -5,053 | -7,987 | -9,079 | -35,371 | -40,207 | -63,553 | -211,411 | -247,597 | -281,449 | -1,479,877 | -1,970,143 | -6,553,741 | -10,359,139 | -45,876,187 | -321,133,309 |
