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 303,432,215, 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 | 303,432,215 | |
| -1 | -303,432,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,432,215.
Example:
1 x 303,432,215 = 303,432,215
and
-1 x -303,432,215 = 303,432,215
Notice both answers equal 303,432,215
With that explanation out of the way, let's continue. Next, we take the number 303,432,215 and divide it by 2:
303,432,215 ÷ 2 = 151,716,107.5
If the quotient is a whole number, then 2 and 151,716,107.5 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 | 303,432,215 | |
| -1 | -303,432,215 |
Now, we try dividing 303,432,215 by 3:
303,432,215 ÷ 3 = 101,144,071.6667
If the quotient is a whole number, then 3 and 101,144,071.6667 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 | 303,432,215 | |
| -1 | -303,432,215 |
Let's try dividing by 4:
303,432,215 ÷ 4 = 75,858,053.75
If the quotient is a whole number, then 4 and 75,858,053.75 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 | 303,432,215 | |
| -1 | 303,432,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 199 | 995 | 4,577 | 13,259 | 22,885 | 66,295 | 304,957 | 1,524,785 | 2,638,541 | 13,192,705 | 60,686,443 | 303,432,215 |
| -1 | -5 | -23 | -115 | -199 | -995 | -4,577 | -13,259 | -22,885 | -66,295 | -304,957 | -1,524,785 | -2,638,541 | -13,192,705 | -60,686,443 | -303,432,215 |
