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 12,336,779, 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 | 12,336,779 | |
| -1 | -12,336,779 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,336,779.
Example:
1 x 12,336,779 = 12,336,779
and
-1 x -12,336,779 = 12,336,779
Notice both answers equal 12,336,779
With that explanation out of the way, let's continue. Next, we take the number 12,336,779 and divide it by 2:
12,336,779 ÷ 2 = 6,168,389.5
If the quotient is a whole number, then 2 and 6,168,389.5 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 | 12,336,779 | |
| -1 | -12,336,779 |
Now, we try dividing 12,336,779 by 3:
12,336,779 ÷ 3 = 4,112,259.6667
If the quotient is a whole number, then 3 and 4,112,259.6667 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 | 12,336,779 | |
| -1 | -12,336,779 |
Let's try dividing by 4:
12,336,779 ÷ 4 = 3,084,194.75
If the quotient is a whole number, then 4 and 3,084,194.75 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 | 12,336,779 | |
| -1 | 12,336,779 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 91 | 107 | 181 | 637 | 749 | 1,267 | 1,391 | 2,353 | 5,243 | 8,869 | 9,737 | 16,471 | 19,367 | 68,159 | 115,297 | 135,569 | 251,771 | 948,983 | 1,762,397 | 12,336,779 |
| -1 | -7 | -13 | -49 | -91 | -107 | -181 | -637 | -749 | -1,267 | -1,391 | -2,353 | -5,243 | -8,869 | -9,737 | -16,471 | -19,367 | -68,159 | -115,297 | -135,569 | -251,771 | -948,983 | -1,762,397 | -12,336,779 |
