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 304,400,311, 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 | 304,400,311 | |
| -1 | -304,400,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,400,311.
Example:
1 x 304,400,311 = 304,400,311
and
-1 x -304,400,311 = 304,400,311
Notice both answers equal 304,400,311
With that explanation out of the way, let's continue. Next, we take the number 304,400,311 and divide it by 2:
304,400,311 ÷ 2 = 152,200,155.5
If the quotient is a whole number, then 2 and 152,200,155.5 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 | 304,400,311 | |
| -1 | -304,400,311 |
Now, we try dividing 304,400,311 by 3:
304,400,311 ÷ 3 = 101,466,770.3333
If the quotient is a whole number, then 3 and 101,466,770.3333 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 | 304,400,311 | |
| -1 | -304,400,311 |
Let's try dividing by 4:
304,400,311 ÷ 4 = 76,100,077.75
If the quotient is a whole number, then 4 and 76,100,077.75 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 | 304,400,311 | |
| -1 | 304,400,311 |
If you did it right, you will end up with this table:
| 1 | 19 | 43 | 229 | 817 | 1,627 | 4,351 | 9,847 | 30,913 | 69,961 | 187,093 | 372,583 | 1,329,259 | 7,079,077 | 16,021,069 | 304,400,311 |
| -1 | -19 | -43 | -229 | -817 | -1,627 | -4,351 | -9,847 | -30,913 | -69,961 | -187,093 | -372,583 | -1,329,259 | -7,079,077 | -16,021,069 | -304,400,311 |
