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 12,328,757, 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 | 12,328,757 | |
| -1 | -12,328,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,328,757.
Example:
1 x 12,328,757 = 12,328,757
and
-1 x -12,328,757 = 12,328,757
Notice both answers equal 12,328,757
With that explanation out of the way, let's continue. Next, we take the number 12,328,757 and divide it by 2:
12,328,757 ÷ 2 = 6,164,378.5
If the quotient is a whole number, then 2 and 6,164,378.5 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 | 12,328,757 | |
| -1 | -12,328,757 |
Now, we try dividing 12,328,757 by 3:
12,328,757 ÷ 3 = 4,109,585.6667
If the quotient is a whole number, then 3 and 4,109,585.6667 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 | 12,328,757 | |
| -1 | -12,328,757 |
Let's try dividing by 4:
12,328,757 ÷ 4 = 3,082,189.25
If the quotient is a whole number, then 4 and 3,082,189.25 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 | 12,328,757 | |
| -1 | 12,328,757 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 313 | 331 | 2,191 | 2,317 | 5,321 | 5,627 | 37,247 | 39,389 | 103,603 | 725,221 | 1,761,251 | 12,328,757 |
| -1 | -7 | -17 | -119 | -313 | -331 | -2,191 | -2,317 | -5,321 | -5,627 | -37,247 | -39,389 | -103,603 | -725,221 | -1,761,251 | -12,328,757 |
