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 11,150,009, 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 | 11,150,009 | |
| -1 | -11,150,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,150,009.
Example:
1 x 11,150,009 = 11,150,009
and
-1 x -11,150,009 = 11,150,009
Notice both answers equal 11,150,009
With that explanation out of the way, let's continue. Next, we take the number 11,150,009 and divide it by 2:
11,150,009 ÷ 2 = 5,575,004.5
If the quotient is a whole number, then 2 and 5,575,004.5 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 | 11,150,009 | |
| -1 | -11,150,009 |
Now, we try dividing 11,150,009 by 3:
11,150,009 ÷ 3 = 3,716,669.6667
If the quotient is a whole number, then 3 and 3,716,669.6667 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 | 11,150,009 | |
| -1 | -11,150,009 |
Let's try dividing by 4:
11,150,009 ÷ 4 = 2,787,502.25
If the quotient is a whole number, then 4 and 2,787,502.25 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 | 11,150,009 | |
| -1 | 11,150,009 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 89 | 299 | 419 | 1,157 | 2,047 | 5,447 | 9,637 | 26,611 | 37,291 | 125,281 | 484,783 | 857,693 | 11,150,009 |
| -1 | -13 | -23 | -89 | -299 | -419 | -1,157 | -2,047 | -5,447 | -9,637 | -26,611 | -37,291 | -125,281 | -484,783 | -857,693 | -11,150,009 |
