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 303,400,199, 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 | 303,400,199 | |
| -1 | -303,400,199 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,400,199.
Example:
1 x 303,400,199 = 303,400,199
and
-1 x -303,400,199 = 303,400,199
Notice both answers equal 303,400,199
With that explanation out of the way, let's continue. Next, we take the number 303,400,199 and divide it by 2:
303,400,199 ÷ 2 = 151,700,099.5
If the quotient is a whole number, then 2 and 151,700,099.5 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 | 303,400,199 | |
| -1 | -303,400,199 |
Now, we try dividing 303,400,199 by 3:
303,400,199 ÷ 3 = 101,133,399.6667
If the quotient is a whole number, then 3 and 101,133,399.6667 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 | 303,400,199 | |
| -1 | -303,400,199 |
Let's try dividing by 4:
303,400,199 ÷ 4 = 75,850,049.75
If the quotient is a whole number, then 4 and 75,850,049.75 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 | 303,400,199 | |
| -1 | 303,400,199 |
If you did it right, you will end up with this table:
| 1 | 23 | 89 | 103 | 1,439 | 2,047 | 2,369 | 9,167 | 33,097 | 128,071 | 148,217 | 210,841 | 2,945,633 | 3,408,991 | 13,191,313 | 303,400,199 |
| -1 | -23 | -89 | -103 | -1,439 | -2,047 | -2,369 | -9,167 | -33,097 | -128,071 | -148,217 | -210,841 | -2,945,633 | -3,408,991 | -13,191,313 | -303,400,199 |
