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 203,231,005, 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 | 203,231,005 | |
| -1 | -203,231,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 203,231,005.
Example:
1 x 203,231,005 = 203,231,005
and
-1 x -203,231,005 = 203,231,005
Notice both answers equal 203,231,005
With that explanation out of the way, let's continue. Next, we take the number 203,231,005 and divide it by 2:
203,231,005 ÷ 2 = 101,615,502.5
If the quotient is a whole number, then 2 and 101,615,502.5 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 | 203,231,005 | |
| -1 | -203,231,005 |
Now, we try dividing 203,231,005 by 3:
203,231,005 ÷ 3 = 67,743,668.3333
If the quotient is a whole number, then 3 and 67,743,668.3333 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 | 203,231,005 | |
| -1 | -203,231,005 |
Let's try dividing by 4:
203,231,005 ÷ 4 = 50,807,751.25
If the quotient is a whole number, then 4 and 50,807,751.25 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 | 203,231,005 | |
| -1 | 203,231,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 97 | 157 | 485 | 785 | 1,649 | 2,669 | 8,245 | 13,345 | 15,229 | 24,649 | 76,145 | 123,245 | 258,893 | 419,033 | 1,294,465 | 2,095,165 | 2,390,953 | 11,954,765 | 40,646,201 | 203,231,005 |
| -1 | -5 | -17 | -85 | -97 | -157 | -485 | -785 | -1,649 | -2,669 | -8,245 | -13,345 | -15,229 | -24,649 | -76,145 | -123,245 | -258,893 | -419,033 | -1,294,465 | -2,095,165 | -2,390,953 | -11,954,765 | -40,646,201 | -203,231,005 |
