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 230,540,245, 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 | 230,540,245 | |
| -1 | -230,540,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,540,245.
Example:
1 x 230,540,245 = 230,540,245
and
-1 x -230,540,245 = 230,540,245
Notice both answers equal 230,540,245
With that explanation out of the way, let's continue. Next, we take the number 230,540,245 and divide it by 2:
230,540,245 ÷ 2 = 115,270,122.5
If the quotient is a whole number, then 2 and 115,270,122.5 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 | 230,540,245 | |
| -1 | -230,540,245 |
Now, we try dividing 230,540,245 by 3:
230,540,245 ÷ 3 = 76,846,748.3333
If the quotient is a whole number, then 3 and 76,846,748.3333 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 | 230,540,245 | |
| -1 | -230,540,245 |
Let's try dividing by 4:
230,540,245 ÷ 4 = 57,635,061.25
If the quotient is a whole number, then 4 and 57,635,061.25 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 | 230,540,245 | |
| -1 | 230,540,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 1,453 | 2,441 | 7,265 | 12,205 | 18,889 | 31,733 | 94,445 | 158,665 | 3,546,773 | 17,733,865 | 46,108,049 | 230,540,245 |
| -1 | -5 | -13 | -65 | -1,453 | -2,441 | -7,265 | -12,205 | -18,889 | -31,733 | -94,445 | -158,665 | -3,546,773 | -17,733,865 | -46,108,049 | -230,540,245 |
