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 323,120,125, 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 | 323,120,125 | |
| -1 | -323,120,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 323,120,125.
Example:
1 x 323,120,125 = 323,120,125
and
-1 x -323,120,125 = 323,120,125
Notice both answers equal 323,120,125
With that explanation out of the way, let's continue. Next, we take the number 323,120,125 and divide it by 2:
323,120,125 ÷ 2 = 161,560,062.5
If the quotient is a whole number, then 2 and 161,560,062.5 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 | 323,120,125 | |
| -1 | -323,120,125 |
Now, we try dividing 323,120,125 by 3:
323,120,125 ÷ 3 = 107,706,708.3333
If the quotient is a whole number, then 3 and 107,706,708.3333 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 | 323,120,125 | |
| -1 | -323,120,125 |
Let's try dividing by 4:
323,120,125 ÷ 4 = 80,780,031.25
If the quotient is a whole number, then 4 and 80,780,031.25 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 | 323,120,125 | |
| -1 | 323,120,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 211 | 1,055 | 5,275 | 12,251 | 26,375 | 61,255 | 306,275 | 1,531,375 | 2,584,961 | 12,924,805 | 64,624,025 | 323,120,125 |
| -1 | -5 | -25 | -125 | -211 | -1,055 | -5,275 | -12,251 | -26,375 | -61,255 | -306,275 | -1,531,375 | -2,584,961 | -12,924,805 | -64,624,025 | -323,120,125 |
