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 166,104,605, 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 | 166,104,605 | |
| -1 | -166,104,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,104,605.
Example:
1 x 166,104,605 = 166,104,605
and
-1 x -166,104,605 = 166,104,605
Notice both answers equal 166,104,605
With that explanation out of the way, let's continue. Next, we take the number 166,104,605 and divide it by 2:
166,104,605 ÷ 2 = 83,052,302.5
If the quotient is a whole number, then 2 and 83,052,302.5 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 | 166,104,605 | |
| -1 | -166,104,605 |
Now, we try dividing 166,104,605 by 3:
166,104,605 ÷ 3 = 55,368,201.6667
If the quotient is a whole number, then 3 and 55,368,201.6667 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 | 166,104,605 | |
| -1 | -166,104,605 |
Let's try dividing by 4:
166,104,605 ÷ 4 = 41,526,151.25
If the quotient is a whole number, then 4 and 41,526,151.25 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 | 166,104,605 | |
| -1 | 166,104,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 181 | 905 | 5,249 | 6,329 | 26,245 | 31,645 | 183,541 | 917,705 | 1,145,549 | 5,727,745 | 33,220,921 | 166,104,605 |
| -1 | -5 | -29 | -145 | -181 | -905 | -5,249 | -6,329 | -26,245 | -31,645 | -183,541 | -917,705 | -1,145,549 | -5,727,745 | -33,220,921 | -166,104,605 |
