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 13,435,331, 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 | 13,435,331 | |
| -1 | -13,435,331 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,435,331.
Example:
1 x 13,435,331 = 13,435,331
and
-1 x -13,435,331 = 13,435,331
Notice both answers equal 13,435,331
With that explanation out of the way, let's continue. Next, we take the number 13,435,331 and divide it by 2:
13,435,331 ÷ 2 = 6,717,665.5
If the quotient is a whole number, then 2 and 6,717,665.5 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 | 13,435,331 | |
| -1 | -13,435,331 |
Now, we try dividing 13,435,331 by 3:
13,435,331 ÷ 3 = 4,478,443.6667
If the quotient is a whole number, then 3 and 4,478,443.6667 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 | 13,435,331 | |
| -1 | -13,435,331 |
Let's try dividing by 4:
13,435,331 ÷ 4 = 3,358,832.75
If the quotient is a whole number, then 4 and 3,358,832.75 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 | 13,435,331 | |
| -1 | 13,435,331 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 41 | 91 | 169 | 277 | 287 | 533 | 1,183 | 1,939 | 3,601 | 3,731 | 6,929 | 11,357 | 25,207 | 46,813 | 48,503 | 79,499 | 147,641 | 327,691 | 1,033,487 | 1,919,333 | 13,435,331 |
| -1 | -7 | -13 | -41 | -91 | -169 | -277 | -287 | -533 | -1,183 | -1,939 | -3,601 | -3,731 | -6,929 | -11,357 | -25,207 | -46,813 | -48,503 | -79,499 | -147,641 | -327,691 | -1,033,487 | -1,919,333 | -13,435,331 |
