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 206,635, 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 | 206,635 | |
| -1 | -206,635 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 206,635.
Example:
1 x 206,635 = 206,635
and
-1 x -206,635 = 206,635
Notice both answers equal 206,635
With that explanation out of the way, let's continue. Next, we take the number 206,635 and divide it by 2:
206,635 ÷ 2 = 103,317.5
If the quotient is a whole number, then 2 and 103,317.5 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 | 206,635 | |
| -1 | -206,635 |
Now, we try dividing 206,635 by 3:
206,635 ÷ 3 = 68,878.3333
If the quotient is a whole number, then 3 and 68,878.3333 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 | 206,635 | |
| -1 | -206,635 |
Let's try dividing by 4:
206,635 ÷ 4 = 51,658.75
If the quotient is a whole number, then 4 and 51,658.75 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 | 206,635 | |
| -1 | 206,635 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 17 | 55 | 65 | 85 | 143 | 187 | 221 | 289 | 715 | 935 | 1,105 | 1,445 | 2,431 | 3,179 | 3,757 | 12,155 | 15,895 | 18,785 | 41,327 | 206,635 |
| -1 | -5 | -11 | -13 | -17 | -55 | -65 | -85 | -143 | -187 | -221 | -289 | -715 | -935 | -1,105 | -1,445 | -2,431 | -3,179 | -3,757 | -12,155 | -15,895 | -18,785 | -41,327 | -206,635 |
