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 13,426,331, 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 | 13,426,331 | |
| -1 | -13,426,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,426,331.
Example:
1 x 13,426,331 = 13,426,331
and
-1 x -13,426,331 = 13,426,331
Notice both answers equal 13,426,331
With that explanation out of the way, let's continue. Next, we take the number 13,426,331 and divide it by 2:
13,426,331 ÷ 2 = 6,713,165.5
If the quotient is a whole number, then 2 and 6,713,165.5 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 | 13,426,331 | |
| -1 | -13,426,331 |
Now, we try dividing 13,426,331 by 3:
13,426,331 ÷ 3 = 4,475,443.6667
If the quotient is a whole number, then 3 and 4,475,443.6667 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 | 13,426,331 | |
| -1 | -13,426,331 |
Let's try dividing by 4:
13,426,331 ÷ 4 = 3,356,582.75
If the quotient is a whole number, then 4 and 3,356,582.75 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 | 13,426,331 | |
| -1 | 13,426,331 |
If you did it right, you will end up with this table:
| 1 | 19 | 53 | 67 | 199 | 1,007 | 1,273 | 3,551 | 3,781 | 10,547 | 13,333 | 67,469 | 200,393 | 253,327 | 706,649 | 13,426,331 |
| -1 | -19 | -53 | -67 | -199 | -1,007 | -1,273 | -3,551 | -3,781 | -10,547 | -13,333 | -67,469 | -200,393 | -253,327 | -706,649 | -13,426,331 |
