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 324,115,433, 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 | 324,115,433 | |
| -1 | -324,115,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 324,115,433.
Example:
1 x 324,115,433 = 324,115,433
and
-1 x -324,115,433 = 324,115,433
Notice both answers equal 324,115,433
With that explanation out of the way, let's continue. Next, we take the number 324,115,433 and divide it by 2:
324,115,433 ÷ 2 = 162,057,716.5
If the quotient is a whole number, then 2 and 162,057,716.5 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 | 324,115,433 | |
| -1 | -324,115,433 |
Now, we try dividing 324,115,433 by 3:
324,115,433 ÷ 3 = 108,038,477.6667
If the quotient is a whole number, then 3 and 108,038,477.6667 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 | 324,115,433 | |
| -1 | -324,115,433 |
Let's try dividing by 4:
324,115,433 ÷ 4 = 81,028,858.25
If the quotient is a whole number, then 4 and 81,028,858.25 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 | 324,115,433 | |
| -1 | 324,115,433 |
If you did it right, you will end up with this table:
| 1 | 19 | 79 | 181 | 1,193 | 1,501 | 3,439 | 14,299 | 22,667 | 94,247 | 215,933 | 271,681 | 1,790,693 | 4,102,727 | 17,058,707 | 324,115,433 |
| -1 | -19 | -79 | -181 | -1,193 | -1,501 | -3,439 | -14,299 | -22,667 | -94,247 | -215,933 | -271,681 | -1,790,693 | -4,102,727 | -17,058,707 | -324,115,433 |
