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 118,847,147, 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 | 118,847,147 | |
| -1 | -118,847,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 118,847,147.
Example:
1 x 118,847,147 = 118,847,147
and
-1 x -118,847,147 = 118,847,147
Notice both answers equal 118,847,147
With that explanation out of the way, let's continue. Next, we take the number 118,847,147 and divide it by 2:
118,847,147 ÷ 2 = 59,423,573.5
If the quotient is a whole number, then 2 and 59,423,573.5 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 | 118,847,147 | |
| -1 | -118,847,147 |
Now, we try dividing 118,847,147 by 3:
118,847,147 ÷ 3 = 39,615,715.6667
If the quotient is a whole number, then 3 and 39,615,715.6667 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 | 118,847,147 | |
| -1 | -118,847,147 |
Let's try dividing by 4:
118,847,147 ÷ 4 = 29,711,786.75
If the quotient is a whole number, then 4 and 29,711,786.75 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 | 118,847,147 | |
| -1 | 118,847,147 |
If you did it right, you will end up with this table:
| 1 | 19 | 53 | 107 | 1,007 | 1,103 | 2,033 | 5,671 | 20,957 | 58,459 | 107,749 | 118,021 | 1,110,721 | 2,242,399 | 6,255,113 | 118,847,147 |
| -1 | -19 | -53 | -107 | -1,007 | -1,103 | -2,033 | -5,671 | -20,957 | -58,459 | -107,749 | -118,021 | -1,110,721 | -2,242,399 | -6,255,113 | -118,847,147 |
