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 581,825, 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 | 581,825 | |
| -1 | -581,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 581,825.
Example:
1 x 581,825 = 581,825
and
-1 x -581,825 = 581,825
Notice both answers equal 581,825
With that explanation out of the way, let's continue. Next, we take the number 581,825 and divide it by 2:
581,825 ÷ 2 = 290,912.5
If the quotient is a whole number, then 2 and 290,912.5 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 | 581,825 | |
| -1 | -581,825 |
Now, we try dividing 581,825 by 3:
581,825 ÷ 3 = 193,941.6667
If the quotient is a whole number, then 3 and 193,941.6667 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 | 581,825 | |
| -1 | -581,825 |
Let's try dividing by 4:
581,825 ÷ 4 = 145,456.25
If the quotient is a whole number, then 4 and 145,456.25 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 | 581,825 | |
| -1 | 581,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 37 | 85 | 185 | 425 | 629 | 925 | 1,369 | 3,145 | 6,845 | 15,725 | 23,273 | 34,225 | 116,365 | 581,825 |
| -1 | -5 | -17 | -25 | -37 | -85 | -185 | -425 | -629 | -925 | -1,369 | -3,145 | -6,845 | -15,725 | -23,273 | -34,225 | -116,365 | -581,825 |
