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 1,205,315, 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 | 1,205,315 | |
| -1 | -1,205,315 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,205,315.
Example:
1 x 1,205,315 = 1,205,315
and
-1 x -1,205,315 = 1,205,315
Notice both answers equal 1,205,315
With that explanation out of the way, let's continue. Next, we take the number 1,205,315 and divide it by 2:
1,205,315 ÷ 2 = 602,657.5
If the quotient is a whole number, then 2 and 602,657.5 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 | 1,205,315 | |
| -1 | -1,205,315 |
Now, we try dividing 1,205,315 by 3:
1,205,315 ÷ 3 = 401,771.6667
If the quotient is a whole number, then 3 and 401,771.6667 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 | 1,205,315 | |
| -1 | -1,205,315 |
Let's try dividing by 4:
1,205,315 ÷ 4 = 301,328.75
If the quotient is a whole number, then 4 and 301,328.75 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 | 1,205,315 | |
| -1 | 1,205,315 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 47 | 115 | 223 | 235 | 1,081 | 1,115 | 5,129 | 5,405 | 10,481 | 25,645 | 52,405 | 241,063 | 1,205,315 |
| -1 | -5 | -23 | -47 | -115 | -223 | -235 | -1,081 | -1,115 | -5,129 | -5,405 | -10,481 | -25,645 | -52,405 | -241,063 | -1,205,315 |
