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 1,040,815, 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 | 1,040,815 | |
| -1 | -1,040,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,040,815.
Example:
1 x 1,040,815 = 1,040,815
and
-1 x -1,040,815 = 1,040,815
Notice both answers equal 1,040,815
With that explanation out of the way, let's continue. Next, we take the number 1,040,815 and divide it by 2:
1,040,815 ÷ 2 = 520,407.5
If the quotient is a whole number, then 2 and 520,407.5 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 | 1,040,815 | |
| -1 | -1,040,815 |
Now, we try dividing 1,040,815 by 3:
1,040,815 ÷ 3 = 346,938.3333
If the quotient is a whole number, then 3 and 346,938.3333 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 | 1,040,815 | |
| -1 | -1,040,815 |
Let's try dividing by 4:
1,040,815 ÷ 4 = 260,203.75
If the quotient is a whole number, then 4 and 260,203.75 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 | 1,040,815 | |
| -1 | 1,040,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 47 | 103 | 215 | 235 | 515 | 2,021 | 4,429 | 4,841 | 10,105 | 22,145 | 24,205 | 208,163 | 1,040,815 |
| -1 | -5 | -43 | -47 | -103 | -215 | -235 | -515 | -2,021 | -4,429 | -4,841 | -10,105 | -22,145 | -24,205 | -208,163 | -1,040,815 |
