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 30,331,235, 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 | 30,331,235 | |
| -1 | -30,331,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,331,235.
Example:
1 x 30,331,235 = 30,331,235
and
-1 x -30,331,235 = 30,331,235
Notice both answers equal 30,331,235
With that explanation out of the way, let's continue. Next, we take the number 30,331,235 and divide it by 2:
30,331,235 ÷ 2 = 15,165,617.5
If the quotient is a whole number, then 2 and 15,165,617.5 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 | 30,331,235 | |
| -1 | -30,331,235 |
Now, we try dividing 30,331,235 by 3:
30,331,235 ÷ 3 = 10,110,411.6667
If the quotient is a whole number, then 3 and 10,110,411.6667 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 | 30,331,235 | |
| -1 | -30,331,235 |
Let's try dividing by 4:
30,331,235 ÷ 4 = 7,582,808.75
If the quotient is a whole number, then 4 and 7,582,808.75 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 | 30,331,235 | |
| -1 | 30,331,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 67 | 335 | 737 | 3,685 | 8,231 | 41,155 | 90,541 | 452,705 | 551,477 | 2,757,385 | 6,066,247 | 30,331,235 |
| -1 | -5 | -11 | -55 | -67 | -335 | -737 | -3,685 | -8,231 | -41,155 | -90,541 | -452,705 | -551,477 | -2,757,385 | -6,066,247 | -30,331,235 |
