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 2,655,485, 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 | 2,655,485 | |
| -1 | -2,655,485 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,655,485.
Example:
1 x 2,655,485 = 2,655,485
and
-1 x -2,655,485 = 2,655,485
Notice both answers equal 2,655,485
With that explanation out of the way, let's continue. Next, we take the number 2,655,485 and divide it by 2:
2,655,485 ÷ 2 = 1,327,742.5
If the quotient is a whole number, then 2 and 1,327,742.5 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 | 2,655,485 | |
| -1 | -2,655,485 |
Now, we try dividing 2,655,485 by 3:
2,655,485 ÷ 3 = 885,161.6667
If the quotient is a whole number, then 3 and 885,161.6667 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 | 2,655,485 | |
| -1 | -2,655,485 |
Let's try dividing by 4:
2,655,485 ÷ 4 = 663,871.25
If the quotient is a whole number, then 4 and 663,871.25 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 | 2,655,485 | |
| -1 | 2,655,485 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 4,463 | 22,315 | 31,241 | 75,871 | 156,205 | 379,355 | 531,097 | 2,655,485 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -4,463 | -22,315 | -31,241 | -75,871 | -156,205 | -379,355 | -531,097 | -2,655,485 |
