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 303,738,437, 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 | 303,738,437 | |
| -1 | -303,738,437 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,738,437.
Example:
1 x 303,738,437 = 303,738,437
and
-1 x -303,738,437 = 303,738,437
Notice both answers equal 303,738,437
With that explanation out of the way, let's continue. Next, we take the number 303,738,437 and divide it by 2:
303,738,437 ÷ 2 = 151,869,218.5
If the quotient is a whole number, then 2 and 151,869,218.5 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 | 303,738,437 | |
| -1 | -303,738,437 |
Now, we try dividing 303,738,437 by 3:
303,738,437 ÷ 3 = 101,246,145.6667
If the quotient is a whole number, then 3 and 101,246,145.6667 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 | 303,738,437 | |
| -1 | -303,738,437 |
Let's try dividing by 4:
303,738,437 ÷ 4 = 75,934,609.25
If the quotient is a whole number, then 4 and 75,934,609.25 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 | 303,738,437 | |
| -1 | 303,738,437 |
If you did it right, you will end up with this table:
| 1 | 23 | 149 | 263 | 337 | 3,427 | 6,049 | 7,751 | 39,187 | 50,213 | 88,631 | 901,301 | 1,154,899 | 2,038,513 | 13,206,019 | 303,738,437 |
| -1 | -23 | -149 | -263 | -337 | -3,427 | -6,049 | -7,751 | -39,187 | -50,213 | -88,631 | -901,301 | -1,154,899 | -2,038,513 | -13,206,019 | -303,738,437 |
