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 323,313,185, 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 | 323,313,185 | |
| -1 | -323,313,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,313,185.
Example:
1 x 323,313,185 = 323,313,185
and
-1 x -323,313,185 = 323,313,185
Notice both answers equal 323,313,185
With that explanation out of the way, let's continue. Next, we take the number 323,313,185 and divide it by 2:
323,313,185 ÷ 2 = 161,656,592.5
If the quotient is a whole number, then 2 and 161,656,592.5 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 | 323,313,185 | |
| -1 | -323,313,185 |
Now, we try dividing 323,313,185 by 3:
323,313,185 ÷ 3 = 107,771,061.6667
If the quotient is a whole number, then 3 and 107,771,061.6667 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 | 323,313,185 | |
| -1 | -323,313,185 |
Let's try dividing by 4:
323,313,185 ÷ 4 = 80,828,296.25
If the quotient is a whole number, then 4 and 80,828,296.25 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 | 323,313,185 | |
| -1 | 323,313,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 1,495 | 216,263 | 1,081,315 | 2,811,419 | 4,974,049 | 14,057,095 | 24,870,245 | 64,662,637 | 323,313,185 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -1,495 | -216,263 | -1,081,315 | -2,811,419 | -4,974,049 | -14,057,095 | -24,870,245 | -64,662,637 | -323,313,185 |
