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 206,664,005, 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 | 206,664,005 | |
| -1 | -206,664,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,664,005.
Example:
1 x 206,664,005 = 206,664,005
and
-1 x -206,664,005 = 206,664,005
Notice both answers equal 206,664,005
With that explanation out of the way, let's continue. Next, we take the number 206,664,005 and divide it by 2:
206,664,005 ÷ 2 = 103,332,002.5
If the quotient is a whole number, then 2 and 103,332,002.5 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 | 206,664,005 | |
| -1 | -206,664,005 |
Now, we try dividing 206,664,005 by 3:
206,664,005 ÷ 3 = 68,888,001.6667
If the quotient is a whole number, then 3 and 68,888,001.6667 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 | 206,664,005 | |
| -1 | -206,664,005 |
Let's try dividing by 4:
206,664,005 ÷ 4 = 51,666,001.25
If the quotient is a whole number, then 4 and 51,666,001.25 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 | 206,664,005 | |
| -1 | 206,664,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 113 | 145 | 565 | 3,277 | 12,613 | 16,385 | 63,065 | 365,777 | 1,425,269 | 1,828,885 | 7,126,345 | 41,332,801 | 206,664,005 |
| -1 | -5 | -29 | -113 | -145 | -565 | -3,277 | -12,613 | -16,385 | -63,065 | -365,777 | -1,425,269 | -1,828,885 | -7,126,345 | -41,332,801 | -206,664,005 |
