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 12,163,177, 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 | 12,163,177 | |
| -1 | -12,163,177 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,163,177.
Example:
1 x 12,163,177 = 12,163,177
and
-1 x -12,163,177 = 12,163,177
Notice both answers equal 12,163,177
With that explanation out of the way, let's continue. Next, we take the number 12,163,177 and divide it by 2:
12,163,177 ÷ 2 = 6,081,588.5
If the quotient is a whole number, then 2 and 6,081,588.5 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 | 12,163,177 | |
| -1 | -12,163,177 |
Now, we try dividing 12,163,177 by 3:
12,163,177 ÷ 3 = 4,054,392.3333
If the quotient is a whole number, then 3 and 4,054,392.3333 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 | 12,163,177 | |
| -1 | -12,163,177 |
Let's try dividing by 4:
12,163,177 ÷ 4 = 3,040,794.25
If the quotient is a whole number, then 4 and 3,040,794.25 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 | 12,163,177 | |
| -1 | 12,163,177 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 47 | 221 | 611 | 799 | 1,171 | 10,387 | 15,223 | 19,907 | 55,037 | 258,791 | 715,481 | 935,629 | 12,163,177 |
| -1 | -13 | -17 | -47 | -221 | -611 | -799 | -1,171 | -10,387 | -15,223 | -19,907 | -55,037 | -258,791 | -715,481 | -935,629 | -12,163,177 |
