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 101,331,125, 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 | 101,331,125 | |
| -1 | -101,331,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 101,331,125.
Example:
1 x 101,331,125 = 101,331,125
and
-1 x -101,331,125 = 101,331,125
Notice both answers equal 101,331,125
With that explanation out of the way, let's continue. Next, we take the number 101,331,125 and divide it by 2:
101,331,125 ÷ 2 = 50,665,562.5
If the quotient is a whole number, then 2 and 50,665,562.5 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 | 101,331,125 | |
| -1 | -101,331,125 |
Now, we try dividing 101,331,125 by 3:
101,331,125 ÷ 3 = 33,777,041.6667
If the quotient is a whole number, then 3 and 33,777,041.6667 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 | 101,331,125 | |
| -1 | -101,331,125 |
Let's try dividing by 4:
101,331,125 ÷ 4 = 25,332,781.25
If the quotient is a whole number, then 4 and 25,332,781.25 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 | 101,331,125 | |
| -1 | 101,331,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 115,807 | 579,035 | 810,649 | 2,895,175 | 4,053,245 | 14,475,875 | 20,266,225 | 101,331,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -115,807 | -579,035 | -810,649 | -2,895,175 | -4,053,245 | -14,475,875 | -20,266,225 | -101,331,125 |
