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 304,310,539, 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 | 304,310,539 | |
| -1 | -304,310,539 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,310,539.
Example:
1 x 304,310,539 = 304,310,539
and
-1 x -304,310,539 = 304,310,539
Notice both answers equal 304,310,539
With that explanation out of the way, let's continue. Next, we take the number 304,310,539 and divide it by 2:
304,310,539 ÷ 2 = 152,155,269.5
If the quotient is a whole number, then 2 and 152,155,269.5 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 | 304,310,539 | |
| -1 | -304,310,539 |
Now, we try dividing 304,310,539 by 3:
304,310,539 ÷ 3 = 101,436,846.3333
If the quotient is a whole number, then 3 and 101,436,846.3333 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 | 304,310,539 | |
| -1 | -304,310,539 |
Let's try dividing by 4:
304,310,539 ÷ 4 = 76,077,634.75
If the quotient is a whole number, then 4 and 76,077,634.75 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 | 304,310,539 | |
| -1 | 304,310,539 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 31 | 299 | 403 | 713 | 9,269 | 32,831 | 426,803 | 755,113 | 1,017,761 | 9,816,469 | 13,230,893 | 23,408,503 | 304,310,539 |
| -1 | -13 | -23 | -31 | -299 | -403 | -713 | -9,269 | -32,831 | -426,803 | -755,113 | -1,017,761 | -9,816,469 | -13,230,893 | -23,408,503 | -304,310,539 |
