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 11,132,209, 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 | 11,132,209 | |
| -1 | -11,132,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,132,209.
Example:
1 x 11,132,209 = 11,132,209
and
-1 x -11,132,209 = 11,132,209
Notice both answers equal 11,132,209
With that explanation out of the way, let's continue. Next, we take the number 11,132,209 and divide it by 2:
11,132,209 ÷ 2 = 5,566,104.5
If the quotient is a whole number, then 2 and 5,566,104.5 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 | 11,132,209 | |
| -1 | -11,132,209 |
Now, we try dividing 11,132,209 by 3:
11,132,209 ÷ 3 = 3,710,736.3333
If the quotient is a whole number, then 3 and 3,710,736.3333 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 | 11,132,209 | |
| -1 | -11,132,209 |
Let's try dividing by 4:
11,132,209 ÷ 4 = 2,783,052.25
If the quotient is a whole number, then 4 and 2,783,052.25 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 | 11,132,209 | |
| -1 | 11,132,209 |
If you did it right, you will end up with this table:
| 1 | 11 | 83 | 89 | 137 | 913 | 979 | 1,507 | 7,387 | 11,371 | 12,193 | 81,257 | 125,081 | 134,123 | 1,012,019 | 11,132,209 |
| -1 | -11 | -83 | -89 | -137 | -913 | -979 | -1,507 | -7,387 | -11,371 | -12,193 | -81,257 | -125,081 | -134,123 | -1,012,019 | -11,132,209 |
