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 12,182,945, 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 | 12,182,945 | |
| -1 | -12,182,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,182,945.
Example:
1 x 12,182,945 = 12,182,945
and
-1 x -12,182,945 = 12,182,945
Notice both answers equal 12,182,945
With that explanation out of the way, let's continue. Next, we take the number 12,182,945 and divide it by 2:
12,182,945 ÷ 2 = 6,091,472.5
If the quotient is a whole number, then 2 and 6,091,472.5 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 | 12,182,945 | |
| -1 | -12,182,945 |
Now, we try dividing 12,182,945 by 3:
12,182,945 ÷ 3 = 4,060,981.6667
If the quotient is a whole number, then 3 and 4,060,981.6667 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 | 12,182,945 | |
| -1 | -12,182,945 |
Let's try dividing by 4:
12,182,945 ÷ 4 = 3,045,736.25
If the quotient is a whole number, then 4 and 3,045,736.25 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 | 12,182,945 | |
| -1 | 12,182,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 67 | 205 | 335 | 887 | 2,747 | 4,435 | 13,735 | 36,367 | 59,429 | 181,835 | 297,145 | 2,436,589 | 12,182,945 |
| -1 | -5 | -41 | -67 | -205 | -335 | -887 | -2,747 | -4,435 | -13,735 | -36,367 | -59,429 | -181,835 | -297,145 | -2,436,589 | -12,182,945 |
