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 230,113,235, 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 | 230,113,235 | |
| -1 | -230,113,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,113,235.
Example:
1 x 230,113,235 = 230,113,235
and
-1 x -230,113,235 = 230,113,235
Notice both answers equal 230,113,235
With that explanation out of the way, let's continue. Next, we take the number 230,113,235 and divide it by 2:
230,113,235 ÷ 2 = 115,056,617.5
If the quotient is a whole number, then 2 and 115,056,617.5 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 | 230,113,235 | |
| -1 | -230,113,235 |
Now, we try dividing 230,113,235 by 3:
230,113,235 ÷ 3 = 76,704,411.6667
If the quotient is a whole number, then 3 and 76,704,411.6667 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 | 230,113,235 | |
| -1 | -230,113,235 |
Let's try dividing by 4:
230,113,235 ÷ 4 = 57,528,308.75
If the quotient is a whole number, then 4 and 57,528,308.75 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 | 230,113,235 | |
| -1 | 230,113,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 617 | 3,085 | 6,781 | 6,787 | 33,905 | 33,935 | 74,591 | 372,955 | 4,183,877 | 20,919,385 | 46,022,647 | 230,113,235 |
| -1 | -5 | -11 | -55 | -617 | -3,085 | -6,781 | -6,787 | -33,905 | -33,935 | -74,591 | -372,955 | -4,183,877 | -20,919,385 | -46,022,647 | -230,113,235 |
