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 303,200,023, 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 | 303,200,023 | |
| -1 | -303,200,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,200,023.
Example:
1 x 303,200,023 = 303,200,023
and
-1 x -303,200,023 = 303,200,023
Notice both answers equal 303,200,023
With that explanation out of the way, let's continue. Next, we take the number 303,200,023 and divide it by 2:
303,200,023 ÷ 2 = 151,600,011.5
If the quotient is a whole number, then 2 and 151,600,011.5 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 | 303,200,023 | |
| -1 | -303,200,023 |
Now, we try dividing 303,200,023 by 3:
303,200,023 ÷ 3 = 101,066,674.3333
If the quotient is a whole number, then 3 and 101,066,674.3333 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 | 303,200,023 | |
| -1 | -303,200,023 |
Let's try dividing by 4:
303,200,023 ÷ 4 = 75,800,005.75
If the quotient is a whole number, then 4 and 75,800,005.75 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 | 303,200,023 | |
| -1 | 303,200,023 |
If you did it right, you will end up with this table:
| 1 | 7 | 167 | 433 | 599 | 1,169 | 3,031 | 4,193 | 72,311 | 100,033 | 259,367 | 506,177 | 700,231 | 1,815,569 | 43,314,289 | 303,200,023 |
| -1 | -7 | -167 | -433 | -599 | -1,169 | -3,031 | -4,193 | -72,311 | -100,033 | -259,367 | -506,177 | -700,231 | -1,815,569 | -43,314,289 | -303,200,023 |
