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 806,785, 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 | 806,785 | |
| -1 | -806,785 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 806,785.
Example:
1 x 806,785 = 806,785
and
-1 x -806,785 = 806,785
Notice both answers equal 806,785
With that explanation out of the way, let's continue. Next, we take the number 806,785 and divide it by 2:
806,785 ÷ 2 = 403,392.5
If the quotient is a whole number, then 2 and 403,392.5 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 | 806,785 | |
| -1 | -806,785 |
Now, we try dividing 806,785 by 3:
806,785 ÷ 3 = 268,928.3333
If the quotient is a whole number, then 3 and 268,928.3333 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 | 806,785 | |
| -1 | -806,785 |
Let's try dividing by 4:
806,785 ÷ 4 = 201,696.25
If the quotient is a whole number, then 4 and 201,696.25 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 | 806,785 | |
| -1 | 806,785 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 49 | 89 | 185 | 245 | 259 | 445 | 623 | 1,295 | 1,813 | 3,115 | 3,293 | 4,361 | 9,065 | 16,465 | 21,805 | 23,051 | 115,255 | 161,357 | 806,785 |
| -1 | -5 | -7 | -35 | -37 | -49 | -89 | -185 | -245 | -259 | -445 | -623 | -1,295 | -1,813 | -3,115 | -3,293 | -4,361 | -9,065 | -16,465 | -21,805 | -23,051 | -115,255 | -161,357 | -806,785 |
