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 809,761, 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 | 809,761 | |
| -1 | -809,761 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 809,761.
Example:
1 x 809,761 = 809,761
and
-1 x -809,761 = 809,761
Notice both answers equal 809,761
With that explanation out of the way, let's continue. Next, we take the number 809,761 and divide it by 2:
809,761 ÷ 2 = 404,880.5
If the quotient is a whole number, then 2 and 404,880.5 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 | 809,761 | |
| -1 | -809,761 |
Now, we try dividing 809,761 by 3:
809,761 ÷ 3 = 269,920.3333
If the quotient is a whole number, then 3 and 269,920.3333 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 | 809,761 | |
| -1 | -809,761 |
Let's try dividing by 4:
809,761 ÷ 4 = 202,440.25
If the quotient is a whole number, then 4 and 202,440.25 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 | 809,761 | |
| -1 | 809,761 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 23 | 109 | 323 | 391 | 437 | 1,853 | 2,071 | 2,507 | 7,429 | 35,207 | 42,619 | 47,633 | 809,761 |
| -1 | -17 | -19 | -23 | -109 | -323 | -391 | -437 | -1,853 | -2,071 | -2,507 | -7,429 | -35,207 | -42,619 | -47,633 | -809,761 |
