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 206,555,573, 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 | 206,555,573 | |
| -1 | -206,555,573 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,555,573.
Example:
1 x 206,555,573 = 206,555,573
and
-1 x -206,555,573 = 206,555,573
Notice both answers equal 206,555,573
With that explanation out of the way, let's continue. Next, we take the number 206,555,573 and divide it by 2:
206,555,573 ÷ 2 = 103,277,786.5
If the quotient is a whole number, then 2 and 103,277,786.5 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 | 206,555,573 | |
| -1 | -206,555,573 |
Now, we try dividing 206,555,573 by 3:
206,555,573 ÷ 3 = 68,851,857.6667
If the quotient is a whole number, then 3 and 68,851,857.6667 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 | 206,555,573 | |
| -1 | -206,555,573 |
Let's try dividing by 4:
206,555,573 ÷ 4 = 51,638,893.25
If the quotient is a whole number, then 4 and 51,638,893.25 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 | 206,555,573 | |
| -1 | 206,555,573 |
If you did it right, you will end up with this table:
| 1 | 7 | 31 | 67 | 217 | 469 | 2,077 | 14,207 | 14,539 | 99,449 | 440,417 | 951,869 | 3,082,919 | 6,663,083 | 29,507,939 | 206,555,573 |
| -1 | -7 | -31 | -67 | -217 | -469 | -2,077 | -14,207 | -14,539 | -99,449 | -440,417 | -951,869 | -3,082,919 | -6,663,083 | -29,507,939 | -206,555,573 |
