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 302,023,105, 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 | 302,023,105 | |
| -1 | -302,023,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,023,105.
Example:
1 x 302,023,105 = 302,023,105
and
-1 x -302,023,105 = 302,023,105
Notice both answers equal 302,023,105
With that explanation out of the way, let's continue. Next, we take the number 302,023,105 and divide it by 2:
302,023,105 ÷ 2 = 151,011,552.5
If the quotient is a whole number, then 2 and 151,011,552.5 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 | 302,023,105 | |
| -1 | -302,023,105 |
Now, we try dividing 302,023,105 by 3:
302,023,105 ÷ 3 = 100,674,368.3333
If the quotient is a whole number, then 3 and 100,674,368.3333 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 | 302,023,105 | |
| -1 | -302,023,105 |
Let's try dividing by 4:
302,023,105 ÷ 4 = 75,505,776.25
If the quotient is a whole number, then 4 and 75,505,776.25 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 | 302,023,105 | |
| -1 | 302,023,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 239 | 1,195 | 4,063 | 14,867 | 20,315 | 74,335 | 252,739 | 1,263,695 | 3,553,213 | 17,766,065 | 60,404,621 | 302,023,105 |
| -1 | -5 | -17 | -85 | -239 | -1,195 | -4,063 | -14,867 | -20,315 | -74,335 | -252,739 | -1,263,695 | -3,553,213 | -17,766,065 | -60,404,621 | -302,023,105 |
