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 206,301,809, 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 | 206,301,809 | |
| -1 | -206,301,809 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,301,809.
Example:
1 x 206,301,809 = 206,301,809
and
-1 x -206,301,809 = 206,301,809
Notice both answers equal 206,301,809
With that explanation out of the way, let's continue. Next, we take the number 206,301,809 and divide it by 2:
206,301,809 ÷ 2 = 103,150,904.5
If the quotient is a whole number, then 2 and 103,150,904.5 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 | 206,301,809 | |
| -1 | -206,301,809 |
Now, we try dividing 206,301,809 by 3:
206,301,809 ÷ 3 = 68,767,269.6667
If the quotient is a whole number, then 3 and 68,767,269.6667 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 | 206,301,809 | |
| -1 | -206,301,809 |
Let's try dividing by 4:
206,301,809 ÷ 4 = 51,575,452.25
If the quotient is a whole number, then 4 and 51,575,452.25 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 | 206,301,809 | |
| -1 | 206,301,809 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 181 | 343 | 1,267 | 3,323 | 8,869 | 23,261 | 62,083 | 162,827 | 601,463 | 1,139,789 | 4,210,241 | 29,471,687 | 206,301,809 |
| -1 | -7 | -49 | -181 | -343 | -1,267 | -3,323 | -8,869 | -23,261 | -62,083 | -162,827 | -601,463 | -1,139,789 | -4,210,241 | -29,471,687 | -206,301,809 |
