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 2,309,909, 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 | 2,309,909 | |
| -1 | -2,309,909 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,309,909.
Example:
1 x 2,309,909 = 2,309,909
and
-1 x -2,309,909 = 2,309,909
Notice both answers equal 2,309,909
With that explanation out of the way, let's continue. Next, we take the number 2,309,909 and divide it by 2:
2,309,909 ÷ 2 = 1,154,954.5
If the quotient is a whole number, then 2 and 1,154,954.5 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 | 2,309,909 | |
| -1 | -2,309,909 |
Now, we try dividing 2,309,909 by 3:
2,309,909 ÷ 3 = 769,969.6667
If the quotient is a whole number, then 3 and 769,969.6667 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 | 2,309,909 | |
| -1 | -2,309,909 |
Let's try dividing by 4:
2,309,909 ÷ 4 = 577,477.25
If the quotient is a whole number, then 4 and 577,477.25 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 | 2,309,909 | |
| -1 | 2,309,909 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 47 | 49 | 59 | 119 | 329 | 413 | 799 | 833 | 1,003 | 2,303 | 2,773 | 2,891 | 5,593 | 7,021 | 19,411 | 39,151 | 47,141 | 49,147 | 135,877 | 329,987 | 2,309,909 |
| -1 | -7 | -17 | -47 | -49 | -59 | -119 | -329 | -413 | -799 | -833 | -1,003 | -2,303 | -2,773 | -2,891 | -5,593 | -7,021 | -19,411 | -39,151 | -47,141 | -49,147 | -135,877 | -329,987 | -2,309,909 |
