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 1,078,259, 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 | 1,078,259 | |
| -1 | -1,078,259 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,078,259.
Example:
1 x 1,078,259 = 1,078,259
and
-1 x -1,078,259 = 1,078,259
Notice both answers equal 1,078,259
With that explanation out of the way, let's continue. Next, we take the number 1,078,259 and divide it by 2:
1,078,259 ÷ 2 = 539,129.5
If the quotient is a whole number, then 2 and 539,129.5 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 | 1,078,259 | |
| -1 | -1,078,259 |
Now, we try dividing 1,078,259 by 3:
1,078,259 ÷ 3 = 359,419.6667
If the quotient is a whole number, then 3 and 359,419.6667 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 | 1,078,259 | |
| -1 | -1,078,259 |
Let's try dividing by 4:
1,078,259 ÷ 4 = 269,564.75
If the quotient is a whole number, then 4 and 269,564.75 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 | 1,078,259 | |
| -1 | 1,078,259 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 41 | 91 | 119 | 221 | 287 | 289 | 533 | 697 | 1,547 | 2,023 | 3,731 | 3,757 | 4,879 | 9,061 | 11,849 | 26,299 | 63,427 | 82,943 | 154,037 | 1,078,259 |
| -1 | -7 | -13 | -17 | -41 | -91 | -119 | -221 | -287 | -289 | -533 | -697 | -1,547 | -2,023 | -3,731 | -3,757 | -4,879 | -9,061 | -11,849 | -26,299 | -63,427 | -82,943 | -154,037 | -1,078,259 |
