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 230,050,015, 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 | 230,050,015 | |
| -1 | -230,050,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,050,015.
Example:
1 x 230,050,015 = 230,050,015
and
-1 x -230,050,015 = 230,050,015
Notice both answers equal 230,050,015
With that explanation out of the way, let's continue. Next, we take the number 230,050,015 and divide it by 2:
230,050,015 ÷ 2 = 115,025,007.5
If the quotient is a whole number, then 2 and 115,025,007.5 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 | 230,050,015 | |
| -1 | -230,050,015 |
Now, we try dividing 230,050,015 by 3:
230,050,015 ÷ 3 = 76,683,338.3333
If the quotient is a whole number, then 3 and 76,683,338.3333 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 | 230,050,015 | |
| -1 | -230,050,015 |
Let's try dividing by 4:
230,050,015 ÷ 4 = 57,512,503.75
If the quotient is a whole number, then 4 and 57,512,503.75 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 | 230,050,015 | |
| -1 | 230,050,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 167 | 835 | 2,171 | 10,855 | 21,193 | 105,965 | 275,509 | 1,377,545 | 3,539,231 | 17,696,155 | 46,010,003 | 230,050,015 |
| -1 | -5 | -13 | -65 | -167 | -835 | -2,171 | -10,855 | -21,193 | -105,965 | -275,509 | -1,377,545 | -3,539,231 | -17,696,155 | -46,010,003 | -230,050,015 |
