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 12,550,765, 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 | 12,550,765 | |
| -1 | -12,550,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,550,765.
Example:
1 x 12,550,765 = 12,550,765
and
-1 x -12,550,765 = 12,550,765
Notice both answers equal 12,550,765
With that explanation out of the way, let's continue. Next, we take the number 12,550,765 and divide it by 2:
12,550,765 ÷ 2 = 6,275,382.5
If the quotient is a whole number, then 2 and 6,275,382.5 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 | 12,550,765 | |
| -1 | -12,550,765 |
Now, we try dividing 12,550,765 by 3:
12,550,765 ÷ 3 = 4,183,588.3333
If the quotient is a whole number, then 3 and 4,183,588.3333 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 | 12,550,765 | |
| -1 | -12,550,765 |
Let's try dividing by 4:
12,550,765 ÷ 4 = 3,137,691.25
If the quotient is a whole number, then 4 and 3,137,691.25 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 | 12,550,765 | |
| -1 | 12,550,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 101 | 145 | 505 | 857 | 2,929 | 4,285 | 14,645 | 24,853 | 86,557 | 124,265 | 432,785 | 2,510,153 | 12,550,765 |
| -1 | -5 | -29 | -101 | -145 | -505 | -857 | -2,929 | -4,285 | -14,645 | -24,853 | -86,557 | -124,265 | -432,785 | -2,510,153 | -12,550,765 |
