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 1,322,345, 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 | 1,322,345 | |
| -1 | -1,322,345 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,322,345.
Example:
1 x 1,322,345 = 1,322,345
and
-1 x -1,322,345 = 1,322,345
Notice both answers equal 1,322,345
With that explanation out of the way, let's continue. Next, we take the number 1,322,345 and divide it by 2:
1,322,345 ÷ 2 = 661,172.5
If the quotient is a whole number, then 2 and 661,172.5 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 | 1,322,345 | |
| -1 | -1,322,345 |
Now, we try dividing 1,322,345 by 3:
1,322,345 ÷ 3 = 440,781.6667
If the quotient is a whole number, then 3 and 440,781.6667 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 | 1,322,345 | |
| -1 | -1,322,345 |
Let's try dividing by 4:
1,322,345 ÷ 4 = 330,586.25
If the quotient is a whole number, then 4 and 330,586.25 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 | 1,322,345 | |
| -1 | 1,322,345 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 47 | 85 | 235 | 331 | 799 | 1,655 | 3,995 | 5,627 | 15,557 | 28,135 | 77,785 | 264,469 | 1,322,345 |
| -1 | -5 | -17 | -47 | -85 | -235 | -331 | -799 | -1,655 | -3,995 | -5,627 | -15,557 | -28,135 | -77,785 | -264,469 | -1,322,345 |
