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 13,082,927, 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 | 13,082,927 | |
| -1 | -13,082,927 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 13,082,927.
Example:
1 x 13,082,927 = 13,082,927
and
-1 x -13,082,927 = 13,082,927
Notice both answers equal 13,082,927
With that explanation out of the way, let's continue. Next, we take the number 13,082,927 and divide it by 2:
13,082,927 ÷ 2 = 6,541,463.5
If the quotient is a whole number, then 2 and 6,541,463.5 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 | 13,082,927 | |
| -1 | -13,082,927 |
Now, we try dividing 13,082,927 by 3:
13,082,927 ÷ 3 = 4,360,975.6667
If the quotient is a whole number, then 3 and 4,360,975.6667 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 | 13,082,927 | |
| -1 | -13,082,927 |
Let's try dividing by 4:
13,082,927 ÷ 4 = 3,270,731.75
If the quotient is a whole number, then 4 and 3,270,731.75 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 | 13,082,927 | |
| -1 | 13,082,927 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 143 | 191 | 479 | 2,101 | 2,483 | 5,269 | 6,227 | 27,313 | 68,497 | 91,489 | 1,006,379 | 1,189,357 | 13,082,927 |
| -1 | -11 | -13 | -143 | -191 | -479 | -2,101 | -2,483 | -5,269 | -6,227 | -27,313 | -68,497 | -91,489 | -1,006,379 | -1,189,357 | -13,082,927 |
