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 303,130,133, 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 | 303,130,133 | |
| -1 | -303,130,133 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,130,133.
Example:
1 x 303,130,133 = 303,130,133
and
-1 x -303,130,133 = 303,130,133
Notice both answers equal 303,130,133
With that explanation out of the way, let's continue. Next, we take the number 303,130,133 and divide it by 2:
303,130,133 ÷ 2 = 151,565,066.5
If the quotient is a whole number, then 2 and 151,565,066.5 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 | 303,130,133 | |
| -1 | -303,130,133 |
Now, we try dividing 303,130,133 by 3:
303,130,133 ÷ 3 = 101,043,377.6667
If the quotient is a whole number, then 3 and 101,043,377.6667 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 | 303,130,133 | |
| -1 | -303,130,133 |
Let's try dividing by 4:
303,130,133 ÷ 4 = 75,782,533.25
If the quotient is a whole number, then 4 and 75,782,533.25 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 | 303,130,133 | |
| -1 | 303,130,133 |
If you did it right, you will end up with this table:
| 1 | 23 | 103 | 199 | 643 | 2,369 | 4,577 | 14,789 | 20,497 | 66,229 | 127,957 | 471,431 | 1,523,267 | 2,943,011 | 13,179,571 | 303,130,133 |
| -1 | -23 | -103 | -199 | -643 | -2,369 | -4,577 | -14,789 | -20,497 | -66,229 | -127,957 | -471,431 | -1,523,267 | -2,943,011 | -13,179,571 | -303,130,133 |
