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 32,394,215, 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 | 32,394,215 | |
| -1 | -32,394,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,394,215.
Example:
1 x 32,394,215 = 32,394,215
and
-1 x -32,394,215 = 32,394,215
Notice both answers equal 32,394,215
With that explanation out of the way, let's continue. Next, we take the number 32,394,215 and divide it by 2:
32,394,215 ÷ 2 = 16,197,107.5
If the quotient is a whole number, then 2 and 16,197,107.5 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 | 32,394,215 | |
| -1 | -32,394,215 |
Now, we try dividing 32,394,215 by 3:
32,394,215 ÷ 3 = 10,798,071.6667
If the quotient is a whole number, then 3 and 10,798,071.6667 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 | 32,394,215 | |
| -1 | -32,394,215 |
Let's try dividing by 4:
32,394,215 ÷ 4 = 8,098,553.75
If the quotient is a whole number, then 4 and 8,098,553.75 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 | 32,394,215 | |
| -1 | 32,394,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 199 | 995 | 1,393 | 4,651 | 6,965 | 23,255 | 32,557 | 162,785 | 925,549 | 4,627,745 | 6,478,843 | 32,394,215 |
| -1 | -5 | -7 | -35 | -199 | -995 | -1,393 | -4,651 | -6,965 | -23,255 | -32,557 | -162,785 | -925,549 | -4,627,745 | -6,478,843 | -32,394,215 |
