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 11,177,845, 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 | 11,177,845 | |
| -1 | -11,177,845 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,177,845.
Example:
1 x 11,177,845 = 11,177,845
and
-1 x -11,177,845 = 11,177,845
Notice both answers equal 11,177,845
With that explanation out of the way, let's continue. Next, we take the number 11,177,845 and divide it by 2:
11,177,845 ÷ 2 = 5,588,922.5
If the quotient is a whole number, then 2 and 5,588,922.5 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 | 11,177,845 | |
| -1 | -11,177,845 |
Now, we try dividing 11,177,845 by 3:
11,177,845 ÷ 3 = 3,725,948.3333
If the quotient is a whole number, then 3 and 3,725,948.3333 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 | 11,177,845 | |
| -1 | -11,177,845 |
Let's try dividing by 4:
11,177,845 ÷ 4 = 2,794,461.25
If the quotient is a whole number, then 4 and 2,794,461.25 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 | 11,177,845 | |
| -1 | 11,177,845 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 59 | 295 | 413 | 2,065 | 5,413 | 27,065 | 37,891 | 189,455 | 319,367 | 1,596,835 | 2,235,569 | 11,177,845 |
| -1 | -5 | -7 | -35 | -59 | -295 | -413 | -2,065 | -5,413 | -27,065 | -37,891 | -189,455 | -319,367 | -1,596,835 | -2,235,569 | -11,177,845 |
