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 1,231,285, 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 | 1,231,285 | |
| -1 | -1,231,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,231,285.
Example:
1 x 1,231,285 = 1,231,285
and
-1 x -1,231,285 = 1,231,285
Notice both answers equal 1,231,285
With that explanation out of the way, let's continue. Next, we take the number 1,231,285 and divide it by 2:
1,231,285 ÷ 2 = 615,642.5
If the quotient is a whole number, then 2 and 615,642.5 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 | 1,231,285 | |
| -1 | -1,231,285 |
Now, we try dividing 1,231,285 by 3:
1,231,285 ÷ 3 = 410,428.3333
If the quotient is a whole number, then 3 and 410,428.3333 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 | 1,231,285 | |
| -1 | -1,231,285 |
Let's try dividing by 4:
1,231,285 ÷ 4 = 307,821.25
If the quotient is a whole number, then 4 and 307,821.25 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 | 1,231,285 | |
| -1 | 1,231,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 61 | 305 | 367 | 671 | 1,835 | 3,355 | 4,037 | 20,185 | 22,387 | 111,935 | 246,257 | 1,231,285 |
| -1 | -5 | -11 | -55 | -61 | -305 | -367 | -671 | -1,835 | -3,355 | -4,037 | -20,185 | -22,387 | -111,935 | -246,257 | -1,231,285 |
