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 810,775, 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 | 810,775 | |
| -1 | -810,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 810,775.
Example:
1 x 810,775 = 810,775
and
-1 x -810,775 = 810,775
Notice both answers equal 810,775
With that explanation out of the way, let's continue. Next, we take the number 810,775 and divide it by 2:
810,775 ÷ 2 = 405,387.5
If the quotient is a whole number, then 2 and 405,387.5 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 | 810,775 | |
| -1 | -810,775 |
Now, we try dividing 810,775 by 3:
810,775 ÷ 3 = 270,258.3333
If the quotient is a whole number, then 3 and 270,258.3333 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 | 810,775 | |
| -1 | -810,775 |
Let's try dividing by 4:
810,775 ÷ 4 = 202,693.75
If the quotient is a whole number, then 4 and 202,693.75 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 | 810,775 | |
| -1 | 810,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 41 | 113 | 175 | 205 | 287 | 565 | 791 | 1,025 | 1,435 | 2,825 | 3,955 | 4,633 | 7,175 | 19,775 | 23,165 | 32,431 | 115,825 | 162,155 | 810,775 |
| -1 | -5 | -7 | -25 | -35 | -41 | -113 | -175 | -205 | -287 | -565 | -791 | -1,025 | -1,435 | -2,825 | -3,955 | -4,633 | -7,175 | -19,775 | -23,165 | -32,431 | -115,825 | -162,155 | -810,775 |
