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 206,622,055, 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 | 206,622,055 | |
| -1 | -206,622,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,622,055.
Example:
1 x 206,622,055 = 206,622,055
and
-1 x -206,622,055 = 206,622,055
Notice both answers equal 206,622,055
With that explanation out of the way, let's continue. Next, we take the number 206,622,055 and divide it by 2:
206,622,055 ÷ 2 = 103,311,027.5
If the quotient is a whole number, then 2 and 103,311,027.5 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 | 206,622,055 | |
| -1 | -206,622,055 |
Now, we try dividing 206,622,055 by 3:
206,622,055 ÷ 3 = 68,874,018.3333
If the quotient is a whole number, then 3 and 68,874,018.3333 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 | 206,622,055 | |
| -1 | -206,622,055 |
Let's try dividing by 4:
206,622,055 ÷ 4 = 51,655,513.75
If the quotient is a whole number, then 4 and 51,655,513.75 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 | 206,622,055 | |
| -1 | 206,622,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 599 | 2,995 | 3,631 | 11,381 | 18,155 | 56,905 | 68,989 | 344,945 | 2,174,969 | 10,874,845 | 41,324,411 | 206,622,055 |
| -1 | -5 | -19 | -95 | -599 | -2,995 | -3,631 | -11,381 | -18,155 | -56,905 | -68,989 | -344,945 | -2,174,969 | -10,874,845 | -41,324,411 | -206,622,055 |
