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 8,002,709, 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 | 8,002,709 | |
| -1 | -8,002,709 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 8,002,709.
Example:
1 x 8,002,709 = 8,002,709
and
-1 x -8,002,709 = 8,002,709
Notice both answers equal 8,002,709
With that explanation out of the way, let's continue. Next, we take the number 8,002,709 and divide it by 2:
8,002,709 ÷ 2 = 4,001,354.5
If the quotient is a whole number, then 2 and 4,001,354.5 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 | 8,002,709 | |
| -1 | -8,002,709 |
Now, we try dividing 8,002,709 by 3:
8,002,709 ÷ 3 = 2,667,569.6667
If the quotient is a whole number, then 3 and 2,667,569.6667 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 | 8,002,709 | |
| -1 | -8,002,709 |
Let's try dividing by 4:
8,002,709 ÷ 4 = 2,000,677.25
If the quotient is a whole number, then 4 and 2,000,677.25 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 | 8,002,709 | |
| -1 | 8,002,709 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 191 | 293 | 2,101 | 2,483 | 3,223 | 3,809 | 27,313 | 41,899 | 55,963 | 615,593 | 727,519 | 8,002,709 |
| -1 | -11 | -13 | -143 | -191 | -293 | -2,101 | -2,483 | -3,223 | -3,809 | -27,313 | -41,899 | -55,963 | -615,593 | -727,519 | -8,002,709 |
