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 302,241,205, 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 | 302,241,205 | |
| -1 | -302,241,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,241,205.
Example:
1 x 302,241,205 = 302,241,205
and
-1 x -302,241,205 = 302,241,205
Notice both answers equal 302,241,205
With that explanation out of the way, let's continue. Next, we take the number 302,241,205 and divide it by 2:
302,241,205 ÷ 2 = 151,120,602.5
If the quotient is a whole number, then 2 and 151,120,602.5 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 | 302,241,205 | |
| -1 | -302,241,205 |
Now, we try dividing 302,241,205 by 3:
302,241,205 ÷ 3 = 100,747,068.3333
If the quotient is a whole number, then 3 and 100,747,068.3333 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 | 302,241,205 | |
| -1 | -302,241,205 |
Let's try dividing by 4:
302,241,205 ÷ 4 = 75,560,301.25
If the quotient is a whole number, then 4 and 75,560,301.25 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 | 302,241,205 | |
| -1 | 302,241,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 2,447 | 3,529 | 12,235 | 17,129 | 17,645 | 24,703 | 85,645 | 123,515 | 8,635,463 | 43,177,315 | 60,448,241 | 302,241,205 |
| -1 | -5 | -7 | -35 | -2,447 | -3,529 | -12,235 | -17,129 | -17,645 | -24,703 | -85,645 | -123,515 | -8,635,463 | -43,177,315 | -60,448,241 | -302,241,205 |
