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 323,231,125, 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 | 323,231,125 | |
| -1 | -323,231,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,231,125.
Example:
1 x 323,231,125 = 323,231,125
and
-1 x -323,231,125 = 323,231,125
Notice both answers equal 323,231,125
With that explanation out of the way, let's continue. Next, we take the number 323,231,125 and divide it by 2:
323,231,125 ÷ 2 = 161,615,562.5
If the quotient is a whole number, then 2 and 161,615,562.5 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 | 323,231,125 | |
| -1 | -323,231,125 |
Now, we try dividing 323,231,125 by 3:
323,231,125 ÷ 3 = 107,743,708.3333
If the quotient is a whole number, then 3 and 107,743,708.3333 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 | 323,231,125 | |
| -1 | -323,231,125 |
Let's try dividing by 4:
323,231,125 ÷ 4 = 80,807,781.25
If the quotient is a whole number, then 4 and 80,807,781.25 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 | 323,231,125 | |
| -1 | 323,231,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 369,407 | 1,847,035 | 2,585,849 | 9,235,175 | 12,929,245 | 46,175,875 | 64,646,225 | 323,231,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -369,407 | -1,847,035 | -2,585,849 | -9,235,175 | -12,929,245 | -46,175,875 | -64,646,225 | -323,231,125 |
