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 11,480,447, 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 | 11,480,447 | |
| -1 | -11,480,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,480,447.
Example:
1 x 11,480,447 = 11,480,447
and
-1 x -11,480,447 = 11,480,447
Notice both answers equal 11,480,447
With that explanation out of the way, let's continue. Next, we take the number 11,480,447 and divide it by 2:
11,480,447 ÷ 2 = 5,740,223.5
If the quotient is a whole number, then 2 and 5,740,223.5 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 | 11,480,447 | |
| -1 | -11,480,447 |
Now, we try dividing 11,480,447 by 3:
11,480,447 ÷ 3 = 3,826,815.6667
If the quotient is a whole number, then 3 and 3,826,815.6667 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 | 11,480,447 | |
| -1 | -11,480,447 |
Let's try dividing by 4:
11,480,447 ÷ 4 = 2,870,111.75
If the quotient is a whole number, then 4 and 2,870,111.75 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 | 11,480,447 | |
| -1 | 11,480,447 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 131 | 257 | 341 | 1,441 | 2,827 | 4,061 | 7,967 | 33,667 | 44,671 | 87,637 | 370,337 | 1,043,677 | 11,480,447 |
| -1 | -11 | -31 | -131 | -257 | -341 | -1,441 | -2,827 | -4,061 | -7,967 | -33,667 | -44,671 | -87,637 | -370,337 | -1,043,677 | -11,480,447 |
