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 2,086,535, 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 | 2,086,535 | |
| -1 | -2,086,535 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,086,535.
Example:
1 x 2,086,535 = 2,086,535
and
-1 x -2,086,535 = 2,086,535
Notice both answers equal 2,086,535
With that explanation out of the way, let's continue. Next, we take the number 2,086,535 and divide it by 2:
2,086,535 ÷ 2 = 1,043,267.5
If the quotient is a whole number, then 2 and 1,043,267.5 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 | 2,086,535 | |
| -1 | -2,086,535 |
Now, we try dividing 2,086,535 by 3:
2,086,535 ÷ 3 = 695,511.6667
If the quotient is a whole number, then 3 and 695,511.6667 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 | 2,086,535 | |
| -1 | -2,086,535 |
Let's try dividing by 4:
2,086,535 ÷ 4 = 521,633.75
If the quotient is a whole number, then 4 and 521,633.75 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 | 2,086,535 | |
| -1 | 2,086,535 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 59 | 295 | 643 | 649 | 3,215 | 3,245 | 7,073 | 35,365 | 37,937 | 189,685 | 417,307 | 2,086,535 |
| -1 | -5 | -11 | -55 | -59 | -295 | -643 | -649 | -3,215 | -3,245 | -7,073 | -35,365 | -37,937 | -189,685 | -417,307 | -2,086,535 |
