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 304,230,031, 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 | 304,230,031 | |
| -1 | -304,230,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,230,031.
Example:
1 x 304,230,031 = 304,230,031
and
-1 x -304,230,031 = 304,230,031
Notice both answers equal 304,230,031
With that explanation out of the way, let's continue. Next, we take the number 304,230,031 and divide it by 2:
304,230,031 ÷ 2 = 152,115,015.5
If the quotient is a whole number, then 2 and 152,115,015.5 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 | 304,230,031 | |
| -1 | -304,230,031 |
Now, we try dividing 304,230,031 by 3:
304,230,031 ÷ 3 = 101,410,010.3333
If the quotient is a whole number, then 3 and 101,410,010.3333 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 | 304,230,031 | |
| -1 | -304,230,031 |
Let's try dividing by 4:
304,230,031 ÷ 4 = 76,057,507.75
If the quotient is a whole number, then 4 and 76,057,507.75 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 | 304,230,031 | |
| -1 | 304,230,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 239 | 301 | 1,673 | 4,229 | 10,277 | 29,603 | 71,939 | 181,847 | 1,010,731 | 1,272,929 | 7,075,117 | 43,461,433 | 304,230,031 |
| -1 | -7 | -43 | -239 | -301 | -1,673 | -4,229 | -10,277 | -29,603 | -71,939 | -181,847 | -1,010,731 | -1,272,929 | -7,075,117 | -43,461,433 | -304,230,031 |
