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 17,755,259, 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 | 17,755,259 | |
| -1 | -17,755,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,755,259.
Example:
1 x 17,755,259 = 17,755,259
and
-1 x -17,755,259 = 17,755,259
Notice both answers equal 17,755,259
With that explanation out of the way, let's continue. Next, we take the number 17,755,259 and divide it by 2:
17,755,259 ÷ 2 = 8,877,629.5
If the quotient is a whole number, then 2 and 8,877,629.5 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 | 17,755,259 | |
| -1 | -17,755,259 |
Now, we try dividing 17,755,259 by 3:
17,755,259 ÷ 3 = 5,918,419.6667
If the quotient is a whole number, then 3 and 5,918,419.6667 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 | 17,755,259 | |
| -1 | -17,755,259 |
Let's try dividing by 4:
17,755,259 ÷ 4 = 4,438,814.75
If the quotient is a whole number, then 4 and 4,438,814.75 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 | 17,755,259 | |
| -1 | 17,755,259 |
If you did it right, you will end up with this table:
| 1 | 17 | 43 | 107 | 227 | 731 | 1,819 | 3,859 | 4,601 | 9,761 | 24,289 | 78,217 | 165,937 | 412,913 | 1,044,427 | 17,755,259 |
| -1 | -17 | -43 | -107 | -227 | -731 | -1,819 | -3,859 | -4,601 | -9,761 | -24,289 | -78,217 | -165,937 | -412,913 | -1,044,427 | -17,755,259 |
