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 231,242,515, 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 | 231,242,515 | |
| -1 | -231,242,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,242,515.
Example:
1 x 231,242,515 = 231,242,515
and
-1 x -231,242,515 = 231,242,515
Notice both answers equal 231,242,515
With that explanation out of the way, let's continue. Next, we take the number 231,242,515 and divide it by 2:
231,242,515 ÷ 2 = 115,621,257.5
If the quotient is a whole number, then 2 and 115,621,257.5 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 | 231,242,515 | |
| -1 | -231,242,515 |
Now, we try dividing 231,242,515 by 3:
231,242,515 ÷ 3 = 77,080,838.3333
If the quotient is a whole number, then 3 and 77,080,838.3333 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 | 231,242,515 | |
| -1 | -231,242,515 |
Let's try dividing by 4:
231,242,515 ÷ 4 = 57,810,628.75
If the quotient is a whole number, then 4 and 57,810,628.75 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 | 231,242,515 | |
| -1 | 231,242,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 107 | 245 | 535 | 749 | 3,745 | 5,243 | 8,821 | 26,215 | 44,105 | 61,747 | 308,735 | 432,229 | 943,847 | 2,161,145 | 4,719,235 | 6,606,929 | 33,034,645 | 46,248,503 | 231,242,515 |
| -1 | -5 | -7 | -35 | -49 | -107 | -245 | -535 | -749 | -3,745 | -5,243 | -8,821 | -26,215 | -44,105 | -61,747 | -308,735 | -432,229 | -943,847 | -2,161,145 | -4,719,235 | -6,606,929 | -33,034,645 | -46,248,503 | -231,242,515 |
