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 12,676,339, 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 | 12,676,339 | |
| -1 | -12,676,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,676,339.
Example:
1 x 12,676,339 = 12,676,339
and
-1 x -12,676,339 = 12,676,339
Notice both answers equal 12,676,339
With that explanation out of the way, let's continue. Next, we take the number 12,676,339 and divide it by 2:
12,676,339 ÷ 2 = 6,338,169.5
If the quotient is a whole number, then 2 and 6,338,169.5 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 | 12,676,339 | |
| -1 | -12,676,339 |
Now, we try dividing 12,676,339 by 3:
12,676,339 ÷ 3 = 4,225,446.3333
If the quotient is a whole number, then 3 and 4,225,446.3333 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 | 12,676,339 | |
| -1 | -12,676,339 |
Let's try dividing by 4:
12,676,339 ÷ 4 = 3,169,084.75
If the quotient is a whole number, then 4 and 3,169,084.75 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 | 12,676,339 | |
| -1 | 12,676,339 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 41 | 221 | 533 | 697 | 1,399 | 9,061 | 18,187 | 23,783 | 57,359 | 309,179 | 745,667 | 975,103 | 12,676,339 |
| -1 | -13 | -17 | -41 | -221 | -533 | -697 | -1,399 | -9,061 | -18,187 | -23,783 | -57,359 | -309,179 | -745,667 | -975,103 | -12,676,339 |
