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 259,259, 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 | 259,259 | |
| -1 | -259,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 259,259.
Example:
1 x 259,259 = 259,259
and
-1 x -259,259 = 259,259
Notice both answers equal 259,259
With that explanation out of the way, let's continue. Next, we take the number 259,259 and divide it by 2:
259,259 ÷ 2 = 129,629.5
If the quotient is a whole number, then 2 and 129,629.5 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 | 259,259 | |
| -1 | -259,259 |
Now, we try dividing 259,259 by 3:
259,259 ÷ 3 = 86,419.6667
If the quotient is a whole number, then 3 and 86,419.6667 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 | 259,259 | |
| -1 | -259,259 |
Let's try dividing by 4:
259,259 ÷ 4 = 64,814.75
If the quotient is a whole number, then 4 and 64,814.75 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 | 259,259 | |
| -1 | 259,259 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 37 | 49 | 77 | 91 | 143 | 259 | 407 | 481 | 539 | 637 | 1,001 | 1,813 | 2,849 | 3,367 | 5,291 | 7,007 | 19,943 | 23,569 | 37,037 | 259,259 |
| -1 | -7 | -11 | -13 | -37 | -49 | -77 | -91 | -143 | -259 | -407 | -481 | -539 | -637 | -1,001 | -1,813 | -2,849 | -3,367 | -5,291 | -7,007 | -19,943 | -23,569 | -37,037 | -259,259 |
