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 11,155,403, 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 | 11,155,403 | |
| -1 | -11,155,403 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,155,403.
Example:
1 x 11,155,403 = 11,155,403
and
-1 x -11,155,403 = 11,155,403
Notice both answers equal 11,155,403
With that explanation out of the way, let's continue. Next, we take the number 11,155,403 and divide it by 2:
11,155,403 ÷ 2 = 5,577,701.5
If the quotient is a whole number, then 2 and 5,577,701.5 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 | 11,155,403 | |
| -1 | -11,155,403 |
Now, we try dividing 11,155,403 by 3:
11,155,403 ÷ 3 = 3,718,467.6667
If the quotient is a whole number, then 3 and 3,718,467.6667 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 | 11,155,403 | |
| -1 | -11,155,403 |
Let's try dividing by 4:
11,155,403 ÷ 4 = 2,788,850.75
If the quotient is a whole number, then 4 and 2,788,850.75 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 | 11,155,403 | |
| -1 | 11,155,403 |
If you did it right, you will end up with this table:
| 1 | 7 | 41 | 47 | 287 | 329 | 827 | 1,927 | 5,789 | 13,489 | 33,907 | 38,869 | 237,349 | 272,083 | 1,593,629 | 11,155,403 |
| -1 | -7 | -41 | -47 | -287 | -329 | -827 | -1,927 | -5,789 | -13,489 | -33,907 | -38,869 | -237,349 | -272,083 | -1,593,629 | -11,155,403 |
