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 11,503,115, 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 | 11,503,115 | |
| -1 | -11,503,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,503,115.
Example:
1 x 11,503,115 = 11,503,115
and
-1 x -11,503,115 = 11,503,115
Notice both answers equal 11,503,115
With that explanation out of the way, let's continue. Next, we take the number 11,503,115 and divide it by 2:
11,503,115 ÷ 2 = 5,751,557.5
If the quotient is a whole number, then 2 and 5,751,557.5 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 | 11,503,115 | |
| -1 | -11,503,115 |
Now, we try dividing 11,503,115 by 3:
11,503,115 ÷ 3 = 3,834,371.6667
If the quotient is a whole number, then 3 and 3,834,371.6667 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 | 11,503,115 | |
| -1 | -11,503,115 |
Let's try dividing by 4:
11,503,115 ÷ 4 = 2,875,778.75
If the quotient is a whole number, then 4 and 2,875,778.75 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 | 11,503,115 | |
| -1 | 11,503,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 37 | 65 | 185 | 481 | 2,405 | 4,783 | 23,915 | 62,179 | 176,971 | 310,895 | 884,855 | 2,300,623 | 11,503,115 |
| -1 | -5 | -13 | -37 | -65 | -185 | -481 | -2,405 | -4,783 | -23,915 | -62,179 | -176,971 | -310,895 | -884,855 | -2,300,623 | -11,503,115 |
