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 118,118,839, 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 | 118,118,839 | |
| -1 | -118,118,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,118,839.
Example:
1 x 118,118,839 = 118,118,839
and
-1 x -118,118,839 = 118,118,839
Notice both answers equal 118,118,839
With that explanation out of the way, let's continue. Next, we take the number 118,118,839 and divide it by 2:
118,118,839 ÷ 2 = 59,059,419.5
If the quotient is a whole number, then 2 and 59,059,419.5 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 | 118,118,839 | |
| -1 | -118,118,839 |
Now, we try dividing 118,118,839 by 3:
118,118,839 ÷ 3 = 39,372,946.3333
If the quotient is a whole number, then 3 and 39,372,946.3333 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 | 118,118,839 | |
| -1 | -118,118,839 |
Let's try dividing by 4:
118,118,839 ÷ 4 = 29,529,709.75
If the quotient is a whole number, then 4 and 29,529,709.75 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 | 118,118,839 | |
| -1 | 118,118,839 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 323 | 361 | 1,013 | 6,137 | 6,859 | 17,221 | 19,247 | 116,603 | 327,199 | 365,693 | 6,216,781 | 6,948,167 | 118,118,839 |
| -1 | -17 | -19 | -323 | -361 | -1,013 | -6,137 | -6,859 | -17,221 | -19,247 | -116,603 | -327,199 | -365,693 | -6,216,781 | -6,948,167 | -118,118,839 |
