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 2,682,685, 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 | 2,682,685 | |
| -1 | -2,682,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,682,685.
Example:
1 x 2,682,685 = 2,682,685
and
-1 x -2,682,685 = 2,682,685
Notice both answers equal 2,682,685
With that explanation out of the way, let's continue. Next, we take the number 2,682,685 and divide it by 2:
2,682,685 ÷ 2 = 1,341,342.5
If the quotient is a whole number, then 2 and 1,341,342.5 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 | 2,682,685 | |
| -1 | -2,682,685 |
Now, we try dividing 2,682,685 by 3:
2,682,685 ÷ 3 = 894,228.3333
If the quotient is a whole number, then 3 and 894,228.3333 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 | 2,682,685 | |
| -1 | -2,682,685 |
Let's try dividing by 4:
2,682,685 ÷ 4 = 670,671.25
If the quotient is a whole number, then 4 and 670,671.25 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 | 2,682,685 | |
| -1 | 2,682,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 629 | 853 | 3,145 | 4,265 | 14,501 | 31,561 | 72,505 | 157,805 | 536,537 | 2,682,685 |
| -1 | -5 | -17 | -37 | -85 | -185 | -629 | -853 | -3,145 | -4,265 | -14,501 | -31,561 | -72,505 | -157,805 | -536,537 | -2,682,685 |
