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 11,650,205, 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 | 11,650,205 | |
| -1 | -11,650,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,650,205.
Example:
1 x 11,650,205 = 11,650,205
and
-1 x -11,650,205 = 11,650,205
Notice both answers equal 11,650,205
With that explanation out of the way, let's continue. Next, we take the number 11,650,205 and divide it by 2:
11,650,205 ÷ 2 = 5,825,102.5
If the quotient is a whole number, then 2 and 5,825,102.5 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 | 11,650,205 | |
| -1 | -11,650,205 |
Now, we try dividing 11,650,205 by 3:
11,650,205 ÷ 3 = 3,883,401.6667
If the quotient is a whole number, then 3 and 3,883,401.6667 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 | 11,650,205 | |
| -1 | -11,650,205 |
Let's try dividing by 4:
11,650,205 ÷ 4 = 2,912,551.25
If the quotient is a whole number, then 4 and 2,912,551.25 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 | 11,650,205 | |
| -1 | 11,650,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 43 | 215 | 301 | 1,505 | 7,741 | 38,705 | 54,187 | 270,935 | 332,863 | 1,664,315 | 2,330,041 | 11,650,205 |
| -1 | -5 | -7 | -35 | -43 | -215 | -301 | -1,505 | -7,741 | -38,705 | -54,187 | -270,935 | -332,863 | -1,664,315 | -2,330,041 | -11,650,205 |
