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 166,330,109, 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 | 166,330,109 | |
| -1 | -166,330,109 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,330,109.
Example:
1 x 166,330,109 = 166,330,109
and
-1 x -166,330,109 = 166,330,109
Notice both answers equal 166,330,109
With that explanation out of the way, let's continue. Next, we take the number 166,330,109 and divide it by 2:
166,330,109 ÷ 2 = 83,165,054.5
If the quotient is a whole number, then 2 and 83,165,054.5 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 | 166,330,109 | |
| -1 | -166,330,109 |
Now, we try dividing 166,330,109 by 3:
166,330,109 ÷ 3 = 55,443,369.6667
If the quotient is a whole number, then 3 and 55,443,369.6667 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 | 166,330,109 | |
| -1 | -166,330,109 |
Let's try dividing by 4:
166,330,109 ÷ 4 = 41,582,527.25
If the quotient is a whole number, then 4 and 41,582,527.25 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 | 166,330,109 | |
| -1 | 166,330,109 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 107 | 121 | 319 | 443 | 1,177 | 3,103 | 3,509 | 4,873 | 12,847 | 12,947 | 34,133 | 47,401 | 53,603 | 141,317 | 375,463 | 521,411 | 1,374,629 | 1,554,487 | 5,735,521 | 15,120,919 | 166,330,109 |
| -1 | -11 | -29 | -107 | -121 | -319 | -443 | -1,177 | -3,103 | -3,509 | -4,873 | -12,847 | -12,947 | -34,133 | -47,401 | -53,603 | -141,317 | -375,463 | -521,411 | -1,374,629 | -1,554,487 | -5,735,521 | -15,120,919 | -166,330,109 |
