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 303,123,073, 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 | 303,123,073 | |
| -1 | -303,123,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,123,073.
Example:
1 x 303,123,073 = 303,123,073
and
-1 x -303,123,073 = 303,123,073
Notice both answers equal 303,123,073
With that explanation out of the way, let's continue. Next, we take the number 303,123,073 and divide it by 2:
303,123,073 ÷ 2 = 151,561,536.5
If the quotient is a whole number, then 2 and 151,561,536.5 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 | 303,123,073 | |
| -1 | -303,123,073 |
Now, we try dividing 303,123,073 by 3:
303,123,073 ÷ 3 = 101,041,024.3333
If the quotient is a whole number, then 3 and 101,041,024.3333 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 | 303,123,073 | |
| -1 | -303,123,073 |
Let's try dividing by 4:
303,123,073 ÷ 4 = 75,780,768.25
If the quotient is a whole number, then 4 and 75,780,768.25 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 | 303,123,073 | |
| -1 | 303,123,073 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 187 | 457 | 3,547 | 5,027 | 7,769 | 39,017 | 60,299 | 85,459 | 663,289 | 1,620,979 | 17,830,769 | 27,556,643 | 303,123,073 |
| -1 | -11 | -17 | -187 | -457 | -3,547 | -5,027 | -7,769 | -39,017 | -60,299 | -85,459 | -663,289 | -1,620,979 | -17,830,769 | -27,556,643 | -303,123,073 |
