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 118,541,849, 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 | 118,541,849 | |
| -1 | -118,541,849 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,541,849.
Example:
1 x 118,541,849 = 118,541,849
and
-1 x -118,541,849 = 118,541,849
Notice both answers equal 118,541,849
With that explanation out of the way, let's continue. Next, we take the number 118,541,849 and divide it by 2:
118,541,849 ÷ 2 = 59,270,924.5
If the quotient is a whole number, then 2 and 59,270,924.5 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 | 118,541,849 | |
| -1 | -118,541,849 |
Now, we try dividing 118,541,849 by 3:
118,541,849 ÷ 3 = 39,513,949.6667
If the quotient is a whole number, then 3 and 39,513,949.6667 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 | 118,541,849 | |
| -1 | -118,541,849 |
Let's try dividing by 4:
118,541,849 ÷ 4 = 29,635,462.25
If the quotient is a whole number, then 4 and 29,635,462.25 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 | 118,541,849 | |
| -1 | 118,541,849 |
If you did it right, you will end up with this table:
| 1 | 47 | 61 | 173 | 239 | 2,867 | 8,131 | 10,553 | 11,233 | 14,579 | 41,347 | 495,991 | 685,213 | 1,943,309 | 2,522,167 | 118,541,849 |
| -1 | -47 | -61 | -173 | -239 | -2,867 | -8,131 | -10,553 | -11,233 | -14,579 | -41,347 | -495,991 | -685,213 | -1,943,309 | -2,522,167 | -118,541,849 |
