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 11,477,809, 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 | 11,477,809 | |
| -1 | -11,477,809 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,477,809.
Example:
1 x 11,477,809 = 11,477,809
and
-1 x -11,477,809 = 11,477,809
Notice both answers equal 11,477,809
With that explanation out of the way, let's continue. Next, we take the number 11,477,809 and divide it by 2:
11,477,809 ÷ 2 = 5,738,904.5
If the quotient is a whole number, then 2 and 5,738,904.5 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 | 11,477,809 | |
| -1 | -11,477,809 |
Now, we try dividing 11,477,809 by 3:
11,477,809 ÷ 3 = 3,825,936.3333
If the quotient is a whole number, then 3 and 3,825,936.3333 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 | 11,477,809 | |
| -1 | -11,477,809 |
Let's try dividing by 4:
11,477,809 ÷ 4 = 2,869,452.25
If the quotient is a whole number, then 4 and 2,869,452.25 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 | 11,477,809 | |
| -1 | 11,477,809 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 109 | 307 | 343 | 763 | 2,149 | 5,341 | 15,043 | 33,463 | 37,387 | 105,301 | 234,241 | 1,639,687 | 11,477,809 |
| -1 | -7 | -49 | -109 | -307 | -343 | -763 | -2,149 | -5,341 | -15,043 | -33,463 | -37,387 | -105,301 | -234,241 | -1,639,687 | -11,477,809 |
