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 2,001,335, 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 | 2,001,335 | |
| -1 | -2,001,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,001,335.
Example:
1 x 2,001,335 = 2,001,335
and
-1 x -2,001,335 = 2,001,335
Notice both answers equal 2,001,335
With that explanation out of the way, let's continue. Next, we take the number 2,001,335 and divide it by 2:
2,001,335 ÷ 2 = 1,000,667.5
If the quotient is a whole number, then 2 and 1,000,667.5 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 | 2,001,335 | |
| -1 | -2,001,335 |
Now, we try dividing 2,001,335 by 3:
2,001,335 ÷ 3 = 667,111.6667
If the quotient is a whole number, then 3 and 667,111.6667 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 | 2,001,335 | |
| -1 | -2,001,335 |
Let's try dividing by 4:
2,001,335 ÷ 4 = 500,333.75
If the quotient is a whole number, then 4 and 500,333.75 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 | 2,001,335 | |
| -1 | 2,001,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 211 | 271 | 1,055 | 1,355 | 1,477 | 1,897 | 7,385 | 9,485 | 57,181 | 285,905 | 400,267 | 2,001,335 |
| -1 | -5 | -7 | -35 | -211 | -271 | -1,055 | -1,355 | -1,477 | -1,897 | -7,385 | -9,485 | -57,181 | -285,905 | -400,267 | -2,001,335 |
