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 12,645,455, 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 | 12,645,455 | |
| -1 | -12,645,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,645,455.
Example:
1 x 12,645,455 = 12,645,455
and
-1 x -12,645,455 = 12,645,455
Notice both answers equal 12,645,455
With that explanation out of the way, let's continue. Next, we take the number 12,645,455 and divide it by 2:
12,645,455 ÷ 2 = 6,322,727.5
If the quotient is a whole number, then 2 and 6,322,727.5 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 | 12,645,455 | |
| -1 | -12,645,455 |
Now, we try dividing 12,645,455 by 3:
12,645,455 ÷ 3 = 4,215,151.6667
If the quotient is a whole number, then 3 and 4,215,151.6667 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 | 12,645,455 | |
| -1 | -12,645,455 |
Let's try dividing by 4:
12,645,455 ÷ 4 = 3,161,363.75
If the quotient is a whole number, then 4 and 3,161,363.75 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 | 12,645,455 | |
| -1 | 12,645,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 179 | 199 | 355 | 895 | 995 | 12,709 | 14,129 | 35,621 | 63,545 | 70,645 | 178,105 | 2,529,091 | 12,645,455 |
| -1 | -5 | -71 | -179 | -199 | -355 | -895 | -995 | -12,709 | -14,129 | -35,621 | -63,545 | -70,645 | -178,105 | -2,529,091 | -12,645,455 |
