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 203,332,649, 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 | 203,332,649 | |
| -1 | -203,332,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,332,649.
Example:
1 x 203,332,649 = 203,332,649
and
-1 x -203,332,649 = 203,332,649
Notice both answers equal 203,332,649
With that explanation out of the way, let's continue. Next, we take the number 203,332,649 and divide it by 2:
203,332,649 ÷ 2 = 101,666,324.5
If the quotient is a whole number, then 2 and 101,666,324.5 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 | 203,332,649 | |
| -1 | -203,332,649 |
Now, we try dividing 203,332,649 by 3:
203,332,649 ÷ 3 = 67,777,549.6667
If the quotient is a whole number, then 3 and 67,777,549.6667 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 | 203,332,649 | |
| -1 | -203,332,649 |
Let's try dividing by 4:
203,332,649 ÷ 4 = 50,833,162.25
If the quotient is a whole number, then 4 and 50,833,162.25 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 | 203,332,649 | |
| -1 | 203,332,649 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 79 | 481 | 1,027 | 2,923 | 5,351 | 37,999 | 69,563 | 197,987 | 422,729 | 2,573,831 | 5,495,477 | 15,640,973 | 203,332,649 |
| -1 | -13 | -37 | -79 | -481 | -1,027 | -2,923 | -5,351 | -37,999 | -69,563 | -197,987 | -422,729 | -2,573,831 | -5,495,477 | -15,640,973 | -203,332,649 |
