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 302,231,305, 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 | 302,231,305 | |
| -1 | -302,231,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,231,305.
Example:
1 x 302,231,305 = 302,231,305
and
-1 x -302,231,305 = 302,231,305
Notice both answers equal 302,231,305
With that explanation out of the way, let's continue. Next, we take the number 302,231,305 and divide it by 2:
302,231,305 ÷ 2 = 151,115,652.5
If the quotient is a whole number, then 2 and 151,115,652.5 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 | 302,231,305 | |
| -1 | -302,231,305 |
Now, we try dividing 302,231,305 by 3:
302,231,305 ÷ 3 = 100,743,768.3333
If the quotient is a whole number, then 3 and 100,743,768.3333 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 | 302,231,305 | |
| -1 | -302,231,305 |
Let's try dividing by 4:
302,231,305 ÷ 4 = 75,557,826.25
If the quotient is a whole number, then 4 and 75,557,826.25 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 | 302,231,305 | |
| -1 | 302,231,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 67 | 215 | 335 | 2,881 | 14,405 | 20,981 | 104,905 | 902,183 | 1,405,727 | 4,510,915 | 7,028,635 | 60,446,261 | 302,231,305 |
| -1 | -5 | -43 | -67 | -215 | -335 | -2,881 | -14,405 | -20,981 | -104,905 | -902,183 | -1,405,727 | -4,510,915 | -7,028,635 | -60,446,261 | -302,231,305 |
