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 17,731,103, 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 | 17,731,103 | |
| -1 | -17,731,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,731,103.
Example:
1 x 17,731,103 = 17,731,103
and
-1 x -17,731,103 = 17,731,103
Notice both answers equal 17,731,103
With that explanation out of the way, let's continue. Next, we take the number 17,731,103 and divide it by 2:
17,731,103 ÷ 2 = 8,865,551.5
If the quotient is a whole number, then 2 and 8,865,551.5 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 | 17,731,103 | |
| -1 | -17,731,103 |
Now, we try dividing 17,731,103 by 3:
17,731,103 ÷ 3 = 5,910,367.6667
If the quotient is a whole number, then 3 and 5,910,367.6667 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 | 17,731,103 | |
| -1 | -17,731,103 |
Let's try dividing by 4:
17,731,103 ÷ 4 = 4,432,775.75
If the quotient is a whole number, then 4 and 4,432,775.75 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 | 17,731,103 | |
| -1 | 17,731,103 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 191 | 193 | 481 | 2,483 | 2,509 | 7,067 | 7,141 | 36,863 | 91,871 | 92,833 | 479,219 | 1,363,931 | 17,731,103 |
| -1 | -13 | -37 | -191 | -193 | -481 | -2,483 | -2,509 | -7,067 | -7,141 | -36,863 | -91,871 | -92,833 | -479,219 | -1,363,931 | -17,731,103 |
