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 304,112,875, 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 | 304,112,875 | |
| -1 | -304,112,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,112,875.
Example:
1 x 304,112,875 = 304,112,875
and
-1 x -304,112,875 = 304,112,875
Notice both answers equal 304,112,875
With that explanation out of the way, let's continue. Next, we take the number 304,112,875 and divide it by 2:
304,112,875 ÷ 2 = 152,056,437.5
If the quotient is a whole number, then 2 and 152,056,437.5 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 | 304,112,875 | |
| -1 | -304,112,875 |
Now, we try dividing 304,112,875 by 3:
304,112,875 ÷ 3 = 101,370,958.3333
If the quotient is a whole number, then 3 and 101,370,958.3333 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 | 304,112,875 | |
| -1 | -304,112,875 |
Let's try dividing by 4:
304,112,875 ÷ 4 = 76,028,218.75
If the quotient is a whole number, then 4 and 76,028,218.75 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 | 304,112,875 | |
| -1 | 304,112,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 221,173 | 1,105,865 | 2,432,903 | 5,529,325 | 12,164,515 | 27,646,625 | 60,822,575 | 304,112,875 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -221,173 | -1,105,865 | -2,432,903 | -5,529,325 | -12,164,515 | -27,646,625 | -60,822,575 | -304,112,875 |
