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 12,862,955, 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 | 12,862,955 | |
| -1 | -12,862,955 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,862,955.
Example:
1 x 12,862,955 = 12,862,955
and
-1 x -12,862,955 = 12,862,955
Notice both answers equal 12,862,955
With that explanation out of the way, let's continue. Next, we take the number 12,862,955 and divide it by 2:
12,862,955 ÷ 2 = 6,431,477.5
If the quotient is a whole number, then 2 and 6,431,477.5 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 | 12,862,955 | |
| -1 | -12,862,955 |
Now, we try dividing 12,862,955 by 3:
12,862,955 ÷ 3 = 4,287,651.6667
If the quotient is a whole number, then 3 and 4,287,651.6667 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 | 12,862,955 | |
| -1 | -12,862,955 |
Let's try dividing by 4:
12,862,955 ÷ 4 = 3,215,738.75
If the quotient is a whole number, then 4 and 3,215,738.75 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 | 12,862,955 | |
| -1 | 12,862,955 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 227 | 1,135 | 1,589 | 1,619 | 7,945 | 8,095 | 11,333 | 56,665 | 367,513 | 1,837,565 | 2,572,591 | 12,862,955 |
| -1 | -5 | -7 | -35 | -227 | -1,135 | -1,589 | -1,619 | -7,945 | -8,095 | -11,333 | -56,665 | -367,513 | -1,837,565 | -2,572,591 | -12,862,955 |
