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 166,252,265, 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 | 166,252,265 | |
| -1 | -166,252,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 166,252,265.
Example:
1 x 166,252,265 = 166,252,265
and
-1 x -166,252,265 = 166,252,265
Notice both answers equal 166,252,265
With that explanation out of the way, let's continue. Next, we take the number 166,252,265 and divide it by 2:
166,252,265 ÷ 2 = 83,126,132.5
If the quotient is a whole number, then 2 and 83,126,132.5 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 | 166,252,265 | |
| -1 | -166,252,265 |
Now, we try dividing 166,252,265 by 3:
166,252,265 ÷ 3 = 55,417,421.6667
If the quotient is a whole number, then 3 and 55,417,421.6667 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 | 166,252,265 | |
| -1 | -166,252,265 |
Let's try dividing by 4:
166,252,265 ÷ 4 = 41,563,066.25
If the quotient is a whole number, then 4 and 41,563,066.25 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 | 166,252,265 | |
| -1 | 166,252,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 59 | 85 | 295 | 1,003 | 5,015 | 33,151 | 165,755 | 563,567 | 1,955,909 | 2,817,835 | 9,779,545 | 33,250,453 | 166,252,265 |
| -1 | -5 | -17 | -59 | -85 | -295 | -1,003 | -5,015 | -33,151 | -165,755 | -563,567 | -1,955,909 | -2,817,835 | -9,779,545 | -33,250,453 | -166,252,265 |
