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 2,555,045, 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 | 2,555,045 | |
| -1 | -2,555,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,555,045.
Example:
1 x 2,555,045 = 2,555,045
and
-1 x -2,555,045 = 2,555,045
Notice both answers equal 2,555,045
With that explanation out of the way, let's continue. Next, we take the number 2,555,045 and divide it by 2:
2,555,045 ÷ 2 = 1,277,522.5
If the quotient is a whole number, then 2 and 1,277,522.5 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 | 2,555,045 | |
| -1 | -2,555,045 |
Now, we try dividing 2,555,045 by 3:
2,555,045 ÷ 3 = 851,681.6667
If the quotient is a whole number, then 3 and 851,681.6667 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 | 2,555,045 | |
| -1 | -2,555,045 |
Let's try dividing by 4:
2,555,045 ÷ 4 = 638,761.25
If the quotient is a whole number, then 4 and 638,761.25 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 | 2,555,045 | |
| -1 | 2,555,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 67 | 145 | 263 | 335 | 1,315 | 1,943 | 7,627 | 9,715 | 17,621 | 38,135 | 88,105 | 511,009 | 2,555,045 |
| -1 | -5 | -29 | -67 | -145 | -263 | -335 | -1,315 | -1,943 | -7,627 | -9,715 | -17,621 | -38,135 | -88,105 | -511,009 | -2,555,045 |
