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 11,331,145, 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 | 11,331,145 | |
| -1 | -11,331,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,331,145.
Example:
1 x 11,331,145 = 11,331,145
and
-1 x -11,331,145 = 11,331,145
Notice both answers equal 11,331,145
With that explanation out of the way, let's continue. Next, we take the number 11,331,145 and divide it by 2:
11,331,145 ÷ 2 = 5,665,572.5
If the quotient is a whole number, then 2 and 5,665,572.5 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 | 11,331,145 | |
| -1 | -11,331,145 |
Now, we try dividing 11,331,145 by 3:
11,331,145 ÷ 3 = 3,777,048.3333
If the quotient is a whole number, then 3 and 3,777,048.3333 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 | 11,331,145 | |
| -1 | -11,331,145 |
Let's try dividing by 4:
11,331,145 ÷ 4 = 2,832,786.25
If the quotient is a whole number, then 4 and 2,832,786.25 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 | 11,331,145 | |
| -1 | 11,331,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 7,529 | 37,645 | 52,703 | 263,515 | 323,747 | 1,618,735 | 2,266,229 | 11,331,145 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -7,529 | -37,645 | -52,703 | -263,515 | -323,747 | -1,618,735 | -2,266,229 | -11,331,145 |
