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 2,026,145, 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 | 2,026,145 | |
| -1 | -2,026,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 2,026,145.
Example:
1 x 2,026,145 = 2,026,145
and
-1 x -2,026,145 = 2,026,145
Notice both answers equal 2,026,145
With that explanation out of the way, let's continue. Next, we take the number 2,026,145 and divide it by 2:
2,026,145 ÷ 2 = 1,013,072.5
If the quotient is a whole number, then 2 and 1,013,072.5 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 | 2,026,145 | |
| -1 | -2,026,145 |
Now, we try dividing 2,026,145 by 3:
2,026,145 ÷ 3 = 675,381.6667
If the quotient is a whole number, then 3 and 675,381.6667 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 | 2,026,145 | |
| -1 | -2,026,145 |
Let's try dividing by 4:
2,026,145 ÷ 4 = 506,536.25
If the quotient is a whole number, then 4 and 506,536.25 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 | 2,026,145 | |
| -1 | 2,026,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 121 | 187 | 197 | 605 | 935 | 985 | 2,057 | 2,167 | 3,349 | 10,285 | 10,835 | 16,745 | 23,837 | 36,839 | 119,185 | 184,195 | 405,229 | 2,026,145 |
| -1 | -5 | -11 | -17 | -55 | -85 | -121 | -187 | -197 | -605 | -935 | -985 | -2,057 | -2,167 | -3,349 | -10,285 | -10,835 | -16,745 | -23,837 | -36,839 | -119,185 | -184,195 | -405,229 | -2,026,145 |
