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 239,338,931, 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 | 239,338,931 | |
| -1 | -239,338,931 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 239,338,931.
Example:
1 x 239,338,931 = 239,338,931
and
-1 x -239,338,931 = 239,338,931
Notice both answers equal 239,338,931
With that explanation out of the way, let's continue. Next, we take the number 239,338,931 and divide it by 2:
239,338,931 ÷ 2 = 119,669,465.5
If the quotient is a whole number, then 2 and 119,669,465.5 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 | 239,338,931 | |
| -1 | -239,338,931 |
Now, we try dividing 239,338,931 by 3:
239,338,931 ÷ 3 = 79,779,643.6667
If the quotient is a whole number, then 3 and 79,779,643.6667 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 | 239,338,931 | |
| -1 | -239,338,931 |
Let's try dividing by 4:
239,338,931 ÷ 4 = 59,834,732.75
If the quotient is a whole number, then 4 and 59,834,732.75 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 | 239,338,931 | |
| -1 | 239,338,931 |
If you did it right, you will end up with this table:
| 1 | 13 | 163 | 179 | 631 | 2,119 | 2,327 | 8,203 | 29,177 | 102,853 | 112,949 | 379,301 | 1,337,089 | 1,468,337 | 18,410,687 | 239,338,931 |
| -1 | -13 | -163 | -179 | -631 | -2,119 | -2,327 | -8,203 | -29,177 | -102,853 | -112,949 | -379,301 | -1,337,089 | -1,468,337 | -18,410,687 | -239,338,931 |
