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 32,310,203, 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 | 32,310,203 | |
| -1 | -32,310,203 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 32,310,203.
Example:
1 x 32,310,203 = 32,310,203
and
-1 x -32,310,203 = 32,310,203
Notice both answers equal 32,310,203
With that explanation out of the way, let's continue. Next, we take the number 32,310,203 and divide it by 2:
32,310,203 ÷ 2 = 16,155,101.5
If the quotient is a whole number, then 2 and 16,155,101.5 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 | 32,310,203 | |
| -1 | -32,310,203 |
Now, we try dividing 32,310,203 by 3:
32,310,203 ÷ 3 = 10,770,067.6667
If the quotient is a whole number, then 3 and 10,770,067.6667 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 | 32,310,203 | |
| -1 | -32,310,203 |
Let's try dividing by 4:
32,310,203 ÷ 4 = 8,077,550.75
If the quotient is a whole number, then 4 and 8,077,550.75 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 | 32,310,203 | |
| -1 | 32,310,203 |
If you did it right, you will end up with this table:
| 1 | 19 | 101 | 113 | 149 | 1,919 | 2,147 | 2,831 | 11,413 | 15,049 | 16,837 | 216,847 | 285,931 | 319,903 | 1,700,537 | 32,310,203 |
| -1 | -19 | -101 | -113 | -149 | -1,919 | -2,147 | -2,831 | -11,413 | -15,049 | -16,837 | -216,847 | -285,931 | -319,903 | -1,700,537 | -32,310,203 |
