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 827,855, 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 | 827,855 | |
| -1 | -827,855 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 827,855.
Example:
1 x 827,855 = 827,855
and
-1 x -827,855 = 827,855
Notice both answers equal 827,855
With that explanation out of the way, let's continue. Next, we take the number 827,855 and divide it by 2:
827,855 ÷ 2 = 413,927.5
If the quotient is a whole number, then 2 and 413,927.5 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 | 827,855 | |
| -1 | -827,855 |
Now, we try dividing 827,855 by 3:
827,855 ÷ 3 = 275,951.6667
If the quotient is a whole number, then 3 and 275,951.6667 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 | 827,855 | |
| -1 | -827,855 |
Let's try dividing by 4:
827,855 ÷ 4 = 206,963.75
If the quotient is a whole number, then 4 and 206,963.75 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 | 827,855 | |
| -1 | 827,855 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 49 | 109 | 155 | 217 | 245 | 545 | 763 | 1,085 | 1,519 | 3,379 | 3,815 | 5,341 | 7,595 | 16,895 | 23,653 | 26,705 | 118,265 | 165,571 | 827,855 |
| -1 | -5 | -7 | -31 | -35 | -49 | -109 | -155 | -217 | -245 | -545 | -763 | -1,085 | -1,519 | -3,379 | -3,815 | -5,341 | -7,595 | -16,895 | -23,653 | -26,705 | -118,265 | -165,571 | -827,855 |
