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 302,505,503, 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 | 302,505,503 | |
| -1 | -302,505,503 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,505,503.
Example:
1 x 302,505,503 = 302,505,503
and
-1 x -302,505,503 = 302,505,503
Notice both answers equal 302,505,503
With that explanation out of the way, let's continue. Next, we take the number 302,505,503 and divide it by 2:
302,505,503 ÷ 2 = 151,252,751.5
If the quotient is a whole number, then 2 and 151,252,751.5 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 | 302,505,503 | |
| -1 | -302,505,503 |
Now, we try dividing 302,505,503 by 3:
302,505,503 ÷ 3 = 100,835,167.6667
If the quotient is a whole number, then 3 and 100,835,167.6667 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 | 302,505,503 | |
| -1 | -302,505,503 |
Let's try dividing by 4:
302,505,503 ÷ 4 = 75,626,375.75
If the quotient is a whole number, then 4 and 75,626,375.75 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 | 302,505,503 | |
| -1 | 302,505,503 |
If you did it right, you will end up with this table:
| 1 | 41 | 53 | 73 | 1,907 | 2,173 | 2,993 | 3,869 | 78,187 | 101,071 | 139,211 | 158,629 | 4,143,911 | 5,707,651 | 7,378,183 | 302,505,503 |
| -1 | -41 | -53 | -73 | -1,907 | -2,173 | -2,993 | -3,869 | -78,187 | -101,071 | -139,211 | -158,629 | -4,143,911 | -5,707,651 | -7,378,183 | -302,505,503 |
