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 1,023,815, 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 | 1,023,815 | |
| -1 | -1,023,815 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,023,815.
Example:
1 x 1,023,815 = 1,023,815
and
-1 x -1,023,815 = 1,023,815
Notice both answers equal 1,023,815
With that explanation out of the way, let's continue. Next, we take the number 1,023,815 and divide it by 2:
1,023,815 ÷ 2 = 511,907.5
If the quotient is a whole number, then 2 and 511,907.5 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 | 1,023,815 | |
| -1 | -1,023,815 |
Now, we try dividing 1,023,815 by 3:
1,023,815 ÷ 3 = 341,271.6667
If the quotient is a whole number, then 3 and 341,271.6667 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 | 1,023,815 | |
| -1 | -1,023,815 |
Let's try dividing by 4:
1,023,815 ÷ 4 = 255,953.75
If the quotient is a whole number, then 4 and 255,953.75 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 | 1,023,815 | |
| -1 | 1,023,815 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 829 | 1,235 | 4,145 | 10,777 | 15,751 | 53,885 | 78,755 | 204,763 | 1,023,815 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -829 | -1,235 | -4,145 | -10,777 | -15,751 | -53,885 | -78,755 | -204,763 | -1,023,815 |
