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 12,313,345, 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 | 12,313,345 | |
| -1 | -12,313,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,313,345.
Example:
1 x 12,313,345 = 12,313,345
and
-1 x -12,313,345 = 12,313,345
Notice both answers equal 12,313,345
With that explanation out of the way, let's continue. Next, we take the number 12,313,345 and divide it by 2:
12,313,345 ÷ 2 = 6,156,672.5
If the quotient is a whole number, then 2 and 6,156,672.5 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 | 12,313,345 | |
| -1 | -12,313,345 |
Now, we try dividing 12,313,345 by 3:
12,313,345 ÷ 3 = 4,104,448.3333
If the quotient is a whole number, then 3 and 4,104,448.3333 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 | 12,313,345 | |
| -1 | -12,313,345 |
Let's try dividing by 4:
12,313,345 ÷ 4 = 3,078,336.25
If the quotient is a whole number, then 4 and 3,078,336.25 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 | 12,313,345 | |
| -1 | 12,313,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 131 | 655 | 1,441 | 1,709 | 7,205 | 8,545 | 18,799 | 93,995 | 223,879 | 1,119,395 | 2,462,669 | 12,313,345 |
| -1 | -5 | -11 | -55 | -131 | -655 | -1,441 | -1,709 | -7,205 | -8,545 | -18,799 | -93,995 | -223,879 | -1,119,395 | -2,462,669 | -12,313,345 |
