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 206,243,555, 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 | 206,243,555 | |
| -1 | -206,243,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,243,555.
Example:
1 x 206,243,555 = 206,243,555
and
-1 x -206,243,555 = 206,243,555
Notice both answers equal 206,243,555
With that explanation out of the way, let's continue. Next, we take the number 206,243,555 and divide it by 2:
206,243,555 ÷ 2 = 103,121,777.5
If the quotient is a whole number, then 2 and 103,121,777.5 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 | 206,243,555 | |
| -1 | -206,243,555 |
Now, we try dividing 206,243,555 by 3:
206,243,555 ÷ 3 = 68,747,851.6667
If the quotient is a whole number, then 3 and 68,747,851.6667 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 | 206,243,555 | |
| -1 | -206,243,555 |
Let's try dividing by 4:
206,243,555 ÷ 4 = 51,560,888.75
If the quotient is a whole number, then 4 and 51,560,888.75 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 | 206,243,555 | |
| -1 | 206,243,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 127 | 635 | 889 | 4,445 | 46,399 | 231,995 | 324,793 | 1,623,965 | 5,892,673 | 29,463,365 | 41,248,711 | 206,243,555 |
| -1 | -5 | -7 | -35 | -127 | -635 | -889 | -4,445 | -46,399 | -231,995 | -324,793 | -1,623,965 | -5,892,673 | -29,463,365 | -41,248,711 | -206,243,555 |
