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 11,338,609, 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 | 11,338,609 | |
| -1 | -11,338,609 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,338,609.
Example:
1 x 11,338,609 = 11,338,609
and
-1 x -11,338,609 = 11,338,609
Notice both answers equal 11,338,609
With that explanation out of the way, let's continue. Next, we take the number 11,338,609 and divide it by 2:
11,338,609 ÷ 2 = 5,669,304.5
If the quotient is a whole number, then 2 and 5,669,304.5 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 | 11,338,609 | |
| -1 | -11,338,609 |
Now, we try dividing 11,338,609 by 3:
11,338,609 ÷ 3 = 3,779,536.3333
If the quotient is a whole number, then 3 and 3,779,536.3333 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 | 11,338,609 | |
| -1 | -11,338,609 |
Let's try dividing by 4:
11,338,609 ÷ 4 = 2,834,652.25
If the quotient is a whole number, then 4 and 2,834,652.25 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 | 11,338,609 | |
| -1 | 11,338,609 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 47 | 391 | 617 | 799 | 1,081 | 10,489 | 14,191 | 18,377 | 28,999 | 241,247 | 492,983 | 666,977 | 11,338,609 |
| -1 | -17 | -23 | -47 | -391 | -617 | -799 | -1,081 | -10,489 | -14,191 | -18,377 | -28,999 | -241,247 | -492,983 | -666,977 | -11,338,609 |
