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 2,584,595, 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 | 2,584,595 | |
| -1 | -2,584,595 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,584,595.
Example:
1 x 2,584,595 = 2,584,595
and
-1 x -2,584,595 = 2,584,595
Notice both answers equal 2,584,595
With that explanation out of the way, let's continue. Next, we take the number 2,584,595 and divide it by 2:
2,584,595 ÷ 2 = 1,292,297.5
If the quotient is a whole number, then 2 and 1,292,297.5 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 | 2,584,595 | |
| -1 | -2,584,595 |
Now, we try dividing 2,584,595 by 3:
2,584,595 ÷ 3 = 861,531.6667
If the quotient is a whole number, then 3 and 861,531.6667 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 | 2,584,595 | |
| -1 | -2,584,595 |
Let's try dividing by 4:
2,584,595 ÷ 4 = 646,148.75
If the quotient is a whole number, then 4 and 646,148.75 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 | 2,584,595 | |
| -1 | 2,584,595 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 2,339 | 11,695 | 30,407 | 39,763 | 152,035 | 198,815 | 516,919 | 2,584,595 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -2,339 | -11,695 | -30,407 | -39,763 | -152,035 | -198,815 | -516,919 | -2,584,595 |
