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 11,246,417, 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 | 11,246,417 | |
| -1 | -11,246,417 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,246,417.
Example:
1 x 11,246,417 = 11,246,417
and
-1 x -11,246,417 = 11,246,417
Notice both answers equal 11,246,417
With that explanation out of the way, let's continue. Next, we take the number 11,246,417 and divide it by 2:
11,246,417 ÷ 2 = 5,623,208.5
If the quotient is a whole number, then 2 and 5,623,208.5 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 | 11,246,417 | |
| -1 | -11,246,417 |
Now, we try dividing 11,246,417 by 3:
11,246,417 ÷ 3 = 3,748,805.6667
If the quotient is a whole number, then 3 and 3,748,805.6667 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 | 11,246,417 | |
| -1 | -11,246,417 |
Let's try dividing by 4:
11,246,417 ÷ 4 = 2,811,604.25
If the quotient is a whole number, then 4 and 2,811,604.25 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 | 11,246,417 | |
| -1 | 11,246,417 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 83 | 91 | 581 | 1,079 | 1,489 | 7,553 | 10,423 | 19,357 | 123,587 | 135,499 | 865,109 | 1,606,631 | 11,246,417 |
| -1 | -7 | -13 | -83 | -91 | -581 | -1,079 | -1,489 | -7,553 | -10,423 | -19,357 | -123,587 | -135,499 | -865,109 | -1,606,631 | -11,246,417 |
