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 11,441,221, 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 | 11,441,221 | |
| -1 | -11,441,221 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,441,221.
Example:
1 x 11,441,221 = 11,441,221
and
-1 x -11,441,221 = 11,441,221
Notice both answers equal 11,441,221
With that explanation out of the way, let's continue. Next, we take the number 11,441,221 and divide it by 2:
11,441,221 ÷ 2 = 5,720,610.5
If the quotient is a whole number, then 2 and 5,720,610.5 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 | 11,441,221 | |
| -1 | -11,441,221 |
Now, we try dividing 11,441,221 by 3:
11,441,221 ÷ 3 = 3,813,740.3333
If the quotient is a whole number, then 3 and 3,813,740.3333 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 | 11,441,221 | |
| -1 | -11,441,221 |
Let's try dividing by 4:
11,441,221 ÷ 4 = 2,860,305.25
If the quotient is a whole number, then 4 and 2,860,305.25 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 | 11,441,221 | |
| -1 | 11,441,221 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 59 | 61 | 187 | 289 | 649 | 671 | 1,003 | 1,037 | 3,179 | 3,599 | 11,033 | 11,407 | 17,051 | 17,629 | 39,589 | 61,183 | 187,561 | 193,919 | 673,013 | 1,040,111 | 11,441,221 |
| -1 | -11 | -17 | -59 | -61 | -187 | -289 | -649 | -671 | -1,003 | -1,037 | -3,179 | -3,599 | -11,033 | -11,407 | -17,051 | -17,629 | -39,589 | -61,183 | -187,561 | -193,919 | -673,013 | -1,040,111 | -11,441,221 |
