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 113,166,109, 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 | 113,166,109 | |
| -1 | -113,166,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 113,166,109.
Example:
1 x 113,166,109 = 113,166,109
and
-1 x -113,166,109 = 113,166,109
Notice both answers equal 113,166,109
With that explanation out of the way, let's continue. Next, we take the number 113,166,109 and divide it by 2:
113,166,109 ÷ 2 = 56,583,054.5
If the quotient is a whole number, then 2 and 56,583,054.5 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 | 113,166,109 | |
| -1 | -113,166,109 |
Now, we try dividing 113,166,109 by 3:
113,166,109 ÷ 3 = 37,722,036.3333
If the quotient is a whole number, then 3 and 37,722,036.3333 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 | 113,166,109 | |
| -1 | -113,166,109 |
Let's try dividing by 4:
113,166,109 ÷ 4 = 28,291,527.25
If the quotient is a whole number, then 4 and 28,291,527.25 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 | 113,166,109 | |
| -1 | 113,166,109 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 41 | 133 | 287 | 779 | 5,453 | 20,753 | 145,271 | 394,307 | 850,873 | 2,760,149 | 5,956,111 | 16,166,587 | 113,166,109 |
| -1 | -7 | -19 | -41 | -133 | -287 | -779 | -5,453 | -20,753 | -145,271 | -394,307 | -850,873 | -2,760,149 | -5,956,111 | -16,166,587 | -113,166,109 |
