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 2,104,235, 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 | 2,104,235 | |
| -1 | -2,104,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,104,235.
Example:
1 x 2,104,235 = 2,104,235
and
-1 x -2,104,235 = 2,104,235
Notice both answers equal 2,104,235
With that explanation out of the way, let's continue. Next, we take the number 2,104,235 and divide it by 2:
2,104,235 ÷ 2 = 1,052,117.5
If the quotient is a whole number, then 2 and 1,052,117.5 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 | 2,104,235 | |
| -1 | -2,104,235 |
Now, we try dividing 2,104,235 by 3:
2,104,235 ÷ 3 = 701,411.6667
If the quotient is a whole number, then 3 and 701,411.6667 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 | 2,104,235 | |
| -1 | -2,104,235 |
Let's try dividing by 4:
2,104,235 ÷ 4 = 526,058.75
If the quotient is a whole number, then 4 and 526,058.75 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 | 2,104,235 | |
| -1 | 2,104,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 59 | 295 | 413 | 1,019 | 2,065 | 5,095 | 7,133 | 35,665 | 60,121 | 300,605 | 420,847 | 2,104,235 |
| -1 | -5 | -7 | -35 | -59 | -295 | -413 | -1,019 | -2,065 | -5,095 | -7,133 | -35,665 | -60,121 | -300,605 | -420,847 | -2,104,235 |
