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 2,027,335, 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 | 2,027,335 | |
| -1 | -2,027,335 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,027,335.
Example:
1 x 2,027,335 = 2,027,335
and
-1 x -2,027,335 = 2,027,335
Notice both answers equal 2,027,335
With that explanation out of the way, let's continue. Next, we take the number 2,027,335 and divide it by 2:
2,027,335 ÷ 2 = 1,013,667.5
If the quotient is a whole number, then 2 and 1,013,667.5 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 | 2,027,335 | |
| -1 | -2,027,335 |
Now, we try dividing 2,027,335 by 3:
2,027,335 ÷ 3 = 675,778.3333
If the quotient is a whole number, then 3 and 675,778.3333 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 | 2,027,335 | |
| -1 | -2,027,335 |
Let's try dividing by 4:
2,027,335 ÷ 4 = 506,833.75
If the quotient is a whole number, then 4 and 506,833.75 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 | 2,027,335 | |
| -1 | 2,027,335 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 61 | 85 | 115 | 289 | 305 | 391 | 1,037 | 1,403 | 1,445 | 1,955 | 5,185 | 6,647 | 7,015 | 17,629 | 23,851 | 33,235 | 88,145 | 119,255 | 405,467 | 2,027,335 |
| -1 | -5 | -17 | -23 | -61 | -85 | -115 | -289 | -305 | -391 | -1,037 | -1,403 | -1,445 | -1,955 | -5,185 | -6,647 | -7,015 | -17,629 | -23,851 | -33,235 | -88,145 | -119,255 | -405,467 | -2,027,335 |
