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 2,001,835, 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 | 2,001,835 | |
| -1 | -2,001,835 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,001,835.
Example:
1 x 2,001,835 = 2,001,835
and
-1 x -2,001,835 = 2,001,835
Notice both answers equal 2,001,835
With that explanation out of the way, let's continue. Next, we take the number 2,001,835 and divide it by 2:
2,001,835 ÷ 2 = 1,000,917.5
If the quotient is a whole number, then 2 and 1,000,917.5 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 | 2,001,835 | |
| -1 | -2,001,835 |
Now, we try dividing 2,001,835 by 3:
2,001,835 ÷ 3 = 667,278.3333
If the quotient is a whole number, then 3 and 667,278.3333 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 | 2,001,835 | |
| -1 | -2,001,835 |
Let's try dividing by 4:
2,001,835 ÷ 4 = 500,458.75
If the quotient is a whole number, then 4 and 500,458.75 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 | 2,001,835 | |
| -1 | 2,001,835 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 2,141 | 10,705 | 23,551 | 36,397 | 117,755 | 181,985 | 400,367 | 2,001,835 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -2,141 | -10,705 | -23,551 | -36,397 | -117,755 | -181,985 | -400,367 | -2,001,835 |
