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 1,322,545, 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 | 1,322,545 | |
| -1 | -1,322,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,322,545.
Example:
1 x 1,322,545 = 1,322,545
and
-1 x -1,322,545 = 1,322,545
Notice both answers equal 1,322,545
With that explanation out of the way, let's continue. Next, we take the number 1,322,545 and divide it by 2:
1,322,545 ÷ 2 = 661,272.5
If the quotient is a whole number, then 2 and 661,272.5 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 | 1,322,545 | |
| -1 | -1,322,545 |
Now, we try dividing 1,322,545 by 3:
1,322,545 ÷ 3 = 440,848.3333
If the quotient is a whole number, then 3 and 440,848.3333 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 | 1,322,545 | |
| -1 | -1,322,545 |
Let's try dividing by 4:
1,322,545 ÷ 4 = 330,636.25
If the quotient is a whole number, then 4 and 330,636.25 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 | 1,322,545 | |
| -1 | 1,322,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 1,303 | 6,515 | 9,121 | 37,787 | 45,605 | 188,935 | 264,509 | 1,322,545 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -1,303 | -6,515 | -9,121 | -37,787 | -45,605 | -188,935 | -264,509 | -1,322,545 |
