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 231,003,241, 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 | 231,003,241 | |
| -1 | -231,003,241 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,003,241.
Example:
1 x 231,003,241 = 231,003,241
and
-1 x -231,003,241 = 231,003,241
Notice both answers equal 231,003,241
With that explanation out of the way, let's continue. Next, we take the number 231,003,241 and divide it by 2:
231,003,241 ÷ 2 = 115,501,620.5
If the quotient is a whole number, then 2 and 115,501,620.5 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 | 231,003,241 | |
| -1 | -231,003,241 |
Now, we try dividing 231,003,241 by 3:
231,003,241 ÷ 3 = 77,001,080.3333
If the quotient is a whole number, then 3 and 77,001,080.3333 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 | 231,003,241 | |
| -1 | -231,003,241 |
Let's try dividing by 4:
231,003,241 ÷ 4 = 57,750,810.25
If the quotient is a whole number, then 4 and 57,750,810.25 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 | 231,003,241 | |
| -1 | 231,003,241 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 181 | 203 | 1,267 | 5,249 | 6,287 | 36,743 | 44,009 | 182,323 | 1,137,947 | 1,276,261 | 7,965,629 | 33,000,463 | 231,003,241 |
| -1 | -7 | -29 | -181 | -203 | -1,267 | -5,249 | -6,287 | -36,743 | -44,009 | -182,323 | -1,137,947 | -1,276,261 | -7,965,629 | -33,000,463 | -231,003,241 |
