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 324,332,315, 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 | 324,332,315 | |
| -1 | -324,332,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,332,315.
Example:
1 x 324,332,315 = 324,332,315
and
-1 x -324,332,315 = 324,332,315
Notice both answers equal 324,332,315
With that explanation out of the way, let's continue. Next, we take the number 324,332,315 and divide it by 2:
324,332,315 ÷ 2 = 162,166,157.5
If the quotient is a whole number, then 2 and 162,166,157.5 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 | 324,332,315 | |
| -1 | -324,332,315 |
Now, we try dividing 324,332,315 by 3:
324,332,315 ÷ 3 = 108,110,771.6667
If the quotient is a whole number, then 3 and 108,110,771.6667 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 | 324,332,315 | |
| -1 | -324,332,315 |
Let's try dividing by 4:
324,332,315 ÷ 4 = 81,083,078.75
If the quotient is a whole number, then 4 and 81,083,078.75 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 | 324,332,315 | |
| -1 | 324,332,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 223 | 1,115 | 5,129 | 12,647 | 25,645 | 63,235 | 290,881 | 1,454,405 | 2,820,281 | 14,101,405 | 64,866,463 | 324,332,315 |
| -1 | -5 | -23 | -115 | -223 | -1,115 | -5,129 | -12,647 | -25,645 | -63,235 | -290,881 | -1,454,405 | -2,820,281 | -14,101,405 | -64,866,463 | -324,332,315 |
