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 234,250,115, 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 | 234,250,115 | |
| -1 | -234,250,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,250,115.
Example:
1 x 234,250,115 = 234,250,115
and
-1 x -234,250,115 = 234,250,115
Notice both answers equal 234,250,115
With that explanation out of the way, let's continue. Next, we take the number 234,250,115 and divide it by 2:
234,250,115 ÷ 2 = 117,125,057.5
If the quotient is a whole number, then 2 and 117,125,057.5 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 | 234,250,115 | |
| -1 | -234,250,115 |
Now, we try dividing 234,250,115 by 3:
234,250,115 ÷ 3 = 78,083,371.6667
If the quotient is a whole number, then 3 and 78,083,371.6667 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 | 234,250,115 | |
| -1 | -234,250,115 |
Let's try dividing by 4:
234,250,115 ÷ 4 = 58,562,528.75
If the quotient is a whole number, then 4 and 58,562,528.75 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 | 234,250,115 | |
| -1 | 234,250,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 47 | 55 | 235 | 517 | 2,585 | 90,619 | 453,095 | 996,809 | 4,259,093 | 4,984,045 | 21,295,465 | 46,850,023 | 234,250,115 |
| -1 | -5 | -11 | -47 | -55 | -235 | -517 | -2,585 | -90,619 | -453,095 | -996,809 | -4,259,093 | -4,984,045 | -21,295,465 | -46,850,023 | -234,250,115 |
