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 11,728,339, 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 | 11,728,339 | |
| -1 | -11,728,339 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,728,339.
Example:
1 x 11,728,339 = 11,728,339
and
-1 x -11,728,339 = 11,728,339
Notice both answers equal 11,728,339
With that explanation out of the way, let's continue. Next, we take the number 11,728,339 and divide it by 2:
11,728,339 ÷ 2 = 5,864,169.5
If the quotient is a whole number, then 2 and 5,864,169.5 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 | 11,728,339 | |
| -1 | -11,728,339 |
Now, we try dividing 11,728,339 by 3:
11,728,339 ÷ 3 = 3,909,446.3333
If the quotient is a whole number, then 3 and 3,909,446.3333 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 | 11,728,339 | |
| -1 | -11,728,339 |
Let's try dividing by 4:
11,728,339 ÷ 4 = 2,932,084.75
If the quotient is a whole number, then 4 and 2,932,084.75 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 | 11,728,339 | |
| -1 | 11,728,339 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 163 | 541 | 1,141 | 3,097 | 3,787 | 10,279 | 21,679 | 71,953 | 88,183 | 617,281 | 1,675,477 | 11,728,339 |
| -1 | -7 | -19 | -133 | -163 | -541 | -1,141 | -3,097 | -3,787 | -10,279 | -21,679 | -71,953 | -88,183 | -617,281 | -1,675,477 | -11,728,339 |
