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 11,423,993, 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 | 11,423,993 | |
| -1 | -11,423,993 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,423,993.
Example:
1 x 11,423,993 = 11,423,993
and
-1 x -11,423,993 = 11,423,993
Notice both answers equal 11,423,993
With that explanation out of the way, let's continue. Next, we take the number 11,423,993 and divide it by 2:
11,423,993 ÷ 2 = 5,711,996.5
If the quotient is a whole number, then 2 and 5,711,996.5 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 | 11,423,993 | |
| -1 | -11,423,993 |
Now, we try dividing 11,423,993 by 3:
11,423,993 ÷ 3 = 3,807,997.6667
If the quotient is a whole number, then 3 and 3,807,997.6667 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 | 11,423,993 | |
| -1 | -11,423,993 |
Let's try dividing by 4:
11,423,993 ÷ 4 = 2,855,998.25
If the quotient is a whole number, then 4 and 2,855,998.25 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 | 11,423,993 | |
| -1 | 11,423,993 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 139 | 199 | 413 | 973 | 1,393 | 8,201 | 11,741 | 27,661 | 57,407 | 82,187 | 193,627 | 1,631,999 | 11,423,993 |
| -1 | -7 | -59 | -139 | -199 | -413 | -973 | -1,393 | -8,201 | -11,741 | -27,661 | -57,407 | -82,187 | -193,627 | -1,631,999 | -11,423,993 |
