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 2,255,825, 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 | 2,255,825 | |
| -1 | -2,255,825 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,255,825.
Example:
1 x 2,255,825 = 2,255,825
and
-1 x -2,255,825 = 2,255,825
Notice both answers equal 2,255,825
With that explanation out of the way, let's continue. Next, we take the number 2,255,825 and divide it by 2:
2,255,825 ÷ 2 = 1,127,912.5
If the quotient is a whole number, then 2 and 1,127,912.5 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 | 2,255,825 | |
| -1 | -2,255,825 |
Now, we try dividing 2,255,825 by 3:
2,255,825 ÷ 3 = 751,941.6667
If the quotient is a whole number, then 3 and 751,941.6667 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 | 2,255,825 | |
| -1 | -2,255,825 |
Let's try dividing by 4:
2,255,825 ÷ 4 = 563,956.25
If the quotient is a whole number, then 4 and 563,956.25 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 | 2,255,825 | |
| -1 | 2,255,825 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 143 | 275 | 325 | 631 | 715 | 3,155 | 3,575 | 6,941 | 8,203 | 15,775 | 34,705 | 41,015 | 90,233 | 173,525 | 205,075 | 451,165 | 2,255,825 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -143 | -275 | -325 | -631 | -715 | -3,155 | -3,575 | -6,941 | -8,203 | -15,775 | -34,705 | -41,015 | -90,233 | -173,525 | -205,075 | -451,165 | -2,255,825 |
