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 304,433,215, 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 | 304,433,215 | |
| -1 | -304,433,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 304,433,215.
Example:
1 x 304,433,215 = 304,433,215
and
-1 x -304,433,215 = 304,433,215
Notice both answers equal 304,433,215
With that explanation out of the way, let's continue. Next, we take the number 304,433,215 and divide it by 2:
304,433,215 ÷ 2 = 152,216,607.5
If the quotient is a whole number, then 2 and 152,216,607.5 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 | 304,433,215 | |
| -1 | -304,433,215 |
Now, we try dividing 304,433,215 by 3:
304,433,215 ÷ 3 = 101,477,738.3333
If the quotient is a whole number, then 3 and 101,477,738.3333 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 | 304,433,215 | |
| -1 | -304,433,215 |
Let's try dividing by 4:
304,433,215 ÷ 4 = 76,108,303.75
If the quotient is a whole number, then 4 and 76,108,303.75 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 | 304,433,215 | |
| -1 | 304,433,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 79 | 295 | 395 | 4,661 | 13,063 | 23,305 | 65,315 | 770,717 | 1,031,977 | 3,853,585 | 5,159,885 | 60,886,643 | 304,433,215 |
| -1 | -5 | -59 | -79 | -295 | -395 | -4,661 | -13,063 | -23,305 | -65,315 | -770,717 | -1,031,977 | -3,853,585 | -5,159,885 | -60,886,643 | -304,433,215 |
