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 11,504,215, 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 | 11,504,215 | |
| -1 | -11,504,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,504,215.
Example:
1 x 11,504,215 = 11,504,215
and
-1 x -11,504,215 = 11,504,215
Notice both answers equal 11,504,215
With that explanation out of the way, let's continue. Next, we take the number 11,504,215 and divide it by 2:
11,504,215 ÷ 2 = 5,752,107.5
If the quotient is a whole number, then 2 and 5,752,107.5 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 | 11,504,215 | |
| -1 | -11,504,215 |
Now, we try dividing 11,504,215 by 3:
11,504,215 ÷ 3 = 3,834,738.3333
If the quotient is a whole number, then 3 and 3,834,738.3333 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 | 11,504,215 | |
| -1 | -11,504,215 |
Let's try dividing by 4:
11,504,215 ÷ 4 = 2,876,053.75
If the quotient is a whole number, then 4 and 2,876,053.75 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 | 11,504,215 | |
| -1 | 11,504,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 83 | 95 | 415 | 1,459 | 1,577 | 7,295 | 7,885 | 27,721 | 121,097 | 138,605 | 605,485 | 2,300,843 | 11,504,215 |
| -1 | -5 | -19 | -83 | -95 | -415 | -1,459 | -1,577 | -7,295 | -7,885 | -27,721 | -121,097 | -138,605 | -605,485 | -2,300,843 | -11,504,215 |
