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 2,027,675, 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 | 2,027,675 | |
| -1 | -2,027,675 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,027,675.
Example:
1 x 2,027,675 = 2,027,675
and
-1 x -2,027,675 = 2,027,675
Notice both answers equal 2,027,675
With that explanation out of the way, let's continue. Next, we take the number 2,027,675 and divide it by 2:
2,027,675 ÷ 2 = 1,013,837.5
If the quotient is a whole number, then 2 and 1,013,837.5 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 | 2,027,675 | |
| -1 | -2,027,675 |
Now, we try dividing 2,027,675 by 3:
2,027,675 ÷ 3 = 675,891.6667
If the quotient is a whole number, then 3 and 675,891.6667 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 | 2,027,675 | |
| -1 | -2,027,675 |
Let's try dividing by 4:
2,027,675 ÷ 4 = 506,918.75
If the quotient is a whole number, then 4 and 506,918.75 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 | 2,027,675 | |
| -1 | 2,027,675 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 25 | 65 | 85 | 221 | 325 | 367 | 425 | 1,105 | 1,835 | 4,771 | 5,525 | 6,239 | 9,175 | 23,855 | 31,195 | 81,107 | 119,275 | 155,975 | 405,535 | 2,027,675 |
| -1 | -5 | -13 | -17 | -25 | -65 | -85 | -221 | -325 | -367 | -425 | -1,105 | -1,835 | -4,771 | -5,525 | -6,239 | -9,175 | -23,855 | -31,195 | -81,107 | -119,275 | -155,975 | -405,535 | -2,027,675 |
