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 322,200,125, 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 | 322,200,125 | |
| -1 | -322,200,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 322,200,125.
Example:
1 x 322,200,125 = 322,200,125
and
-1 x -322,200,125 = 322,200,125
Notice both answers equal 322,200,125
With that explanation out of the way, let's continue. Next, we take the number 322,200,125 and divide it by 2:
322,200,125 ÷ 2 = 161,100,062.5
If the quotient is a whole number, then 2 and 161,100,062.5 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 | 322,200,125 | |
| -1 | -322,200,125 |
Now, we try dividing 322,200,125 by 3:
322,200,125 ÷ 3 = 107,400,041.6667
If the quotient is a whole number, then 3 and 107,400,041.6667 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 | 322,200,125 | |
| -1 | -322,200,125 |
Let's try dividing by 4:
322,200,125 ÷ 4 = 80,550,031.25
If the quotient is a whole number, then 4 and 80,550,031.25 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 | 322,200,125 | |
| -1 | 322,200,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 125 | 325 | 1,625 | 198,277 | 991,385 | 2,577,601 | 4,956,925 | 12,888,005 | 24,784,625 | 64,440,025 | 322,200,125 |
| -1 | -5 | -13 | -25 | -65 | -125 | -325 | -1,625 | -198,277 | -991,385 | -2,577,601 | -4,956,925 | -12,888,005 | -24,784,625 | -64,440,025 | -322,200,125 |
