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 322,322,125, 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 | 322,322,125 | |
| -1 | -322,322,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,322,125.
Example:
1 x 322,322,125 = 322,322,125
and
-1 x -322,322,125 = 322,322,125
Notice both answers equal 322,322,125
With that explanation out of the way, let's continue. Next, we take the number 322,322,125 and divide it by 2:
322,322,125 ÷ 2 = 161,161,062.5
If the quotient is a whole number, then 2 and 161,161,062.5 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 | 322,322,125 | |
| -1 | -322,322,125 |
Now, we try dividing 322,322,125 by 3:
322,322,125 ÷ 3 = 107,440,708.3333
If the quotient is a whole number, then 3 and 107,440,708.3333 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 | 322,322,125 | |
| -1 | -322,322,125 |
Let's try dividing by 4:
322,322,125 ÷ 4 = 80,580,531.25
If the quotient is a whole number, then 4 and 80,580,531.25 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 | 322,322,125 | |
| -1 | 322,322,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 425 | 2,125 | 151,681 | 758,405 | 2,578,577 | 3,792,025 | 12,892,885 | 18,960,125 | 64,464,425 | 322,322,125 |
| -1 | -5 | -17 | -25 | -85 | -125 | -425 | -2,125 | -151,681 | -758,405 | -2,578,577 | -3,792,025 | -12,892,885 | -18,960,125 | -64,464,425 | -322,322,125 |
