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 8,279,089, 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 | 8,279,089 | |
| -1 | -8,279,089 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,279,089.
Example:
1 x 8,279,089 = 8,279,089
and
-1 x -8,279,089 = 8,279,089
Notice both answers equal 8,279,089
With that explanation out of the way, let's continue. Next, we take the number 8,279,089 and divide it by 2:
8,279,089 ÷ 2 = 4,139,544.5
If the quotient is a whole number, then 2 and 4,139,544.5 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 | 8,279,089 | |
| -1 | -8,279,089 |
Now, we try dividing 8,279,089 by 3:
8,279,089 ÷ 3 = 2,759,696.3333
If the quotient is a whole number, then 3 and 2,759,696.3333 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 | 8,279,089 | |
| -1 | -8,279,089 |
Let's try dividing by 4:
8,279,089 ÷ 4 = 2,069,772.25
If the quotient is a whole number, then 4 and 2,069,772.25 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 | 8,279,089 | |
| -1 | 8,279,089 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 41 | 49 | 91 | 287 | 317 | 533 | 637 | 2,009 | 2,219 | 3,731 | 4,121 | 12,997 | 15,533 | 26,117 | 28,847 | 90,979 | 168,961 | 201,929 | 636,853 | 1,182,727 | 8,279,089 |
| -1 | -7 | -13 | -41 | -49 | -91 | -287 | -317 | -533 | -637 | -2,009 | -2,219 | -3,731 | -4,121 | -12,997 | -15,533 | -26,117 | -28,847 | -90,979 | -168,961 | -201,929 | -636,853 | -1,182,727 | -8,279,089 |
