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 103,022,125, 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 | 103,022,125 | |
| -1 | -103,022,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,022,125.
Example:
1 x 103,022,125 = 103,022,125
and
-1 x -103,022,125 = 103,022,125
Notice both answers equal 103,022,125
With that explanation out of the way, let's continue. Next, we take the number 103,022,125 and divide it by 2:
103,022,125 ÷ 2 = 51,511,062.5
If the quotient is a whole number, then 2 and 51,511,062.5 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 | 103,022,125 | |
| -1 | -103,022,125 |
Now, we try dividing 103,022,125 by 3:
103,022,125 ÷ 3 = 34,340,708.3333
If the quotient is a whole number, then 3 and 34,340,708.3333 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 | 103,022,125 | |
| -1 | -103,022,125 |
Let's try dividing by 4:
103,022,125 ÷ 4 = 25,755,531.25
If the quotient is a whole number, then 4 and 25,755,531.25 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 | 103,022,125 | |
| -1 | 103,022,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 425 | 2,125 | 48,481 | 242,405 | 824,177 | 1,212,025 | 4,120,885 | 6,060,125 | 20,604,425 | 103,022,125 |
| -1 | -5 | -17 | -25 | -85 | -125 | -425 | -2,125 | -48,481 | -242,405 | -824,177 | -1,212,025 | -4,120,885 | -6,060,125 | -20,604,425 | -103,022,125 |
