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 12,326,765, 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 | 12,326,765 | |
| -1 | -12,326,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,326,765.
Example:
1 x 12,326,765 = 12,326,765
and
-1 x -12,326,765 = 12,326,765
Notice both answers equal 12,326,765
With that explanation out of the way, let's continue. Next, we take the number 12,326,765 and divide it by 2:
12,326,765 ÷ 2 = 6,163,382.5
If the quotient is a whole number, then 2 and 6,163,382.5 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 | 12,326,765 | |
| -1 | -12,326,765 |
Now, we try dividing 12,326,765 by 3:
12,326,765 ÷ 3 = 4,108,921.6667
If the quotient is a whole number, then 3 and 4,108,921.6667 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 | 12,326,765 | |
| -1 | -12,326,765 |
Let's try dividing by 4:
12,326,765 ÷ 4 = 3,081,691.25
If the quotient is a whole number, then 4 and 3,081,691.25 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 | 12,326,765 | |
| -1 | 12,326,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 79 | 395 | 869 | 2,837 | 4,345 | 14,185 | 31,207 | 156,035 | 224,123 | 1,120,615 | 2,465,353 | 12,326,765 |
| -1 | -5 | -11 | -55 | -79 | -395 | -869 | -2,837 | -4,345 | -14,185 | -31,207 | -156,035 | -224,123 | -1,120,615 | -2,465,353 | -12,326,765 |
