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 2,585,555, 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 | 2,585,555 | |
| -1 | -2,585,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,585,555.
Example:
1 x 2,585,555 = 2,585,555
and
-1 x -2,585,555 = 2,585,555
Notice both answers equal 2,585,555
With that explanation out of the way, let's continue. Next, we take the number 2,585,555 and divide it by 2:
2,585,555 ÷ 2 = 1,292,777.5
If the quotient is a whole number, then 2 and 1,292,777.5 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 | 2,585,555 | |
| -1 | -2,585,555 |
Now, we try dividing 2,585,555 by 3:
2,585,555 ÷ 3 = 861,851.6667
If the quotient is a whole number, then 3 and 861,851.6667 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 | 2,585,555 | |
| -1 | -2,585,555 |
Let's try dividing by 4:
2,585,555 ÷ 4 = 646,388.75
If the quotient is a whole number, then 4 and 646,388.75 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 | 2,585,555 | |
| -1 | 2,585,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 2,383 | 11,915 | 16,681 | 73,873 | 83,405 | 369,365 | 517,111 | 2,585,555 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -2,383 | -11,915 | -16,681 | -73,873 | -83,405 | -369,365 | -517,111 | -2,585,555 |
