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 230,460,755, 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 | 230,460,755 | |
| -1 | -230,460,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,460,755.
Example:
1 x 230,460,755 = 230,460,755
and
-1 x -230,460,755 = 230,460,755
Notice both answers equal 230,460,755
With that explanation out of the way, let's continue. Next, we take the number 230,460,755 and divide it by 2:
230,460,755 ÷ 2 = 115,230,377.5
If the quotient is a whole number, then 2 and 115,230,377.5 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 | 230,460,755 | |
| -1 | -230,460,755 |
Now, we try dividing 230,460,755 by 3:
230,460,755 ÷ 3 = 76,820,251.6667
If the quotient is a whole number, then 3 and 76,820,251.6667 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 | 230,460,755 | |
| -1 | -230,460,755 |
Let's try dividing by 4:
230,460,755 ÷ 4 = 57,615,188.75
If the quotient is a whole number, then 4 and 57,615,188.75 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 | 230,460,755 | |
| -1 | 230,460,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 387,329 | 1,936,645 | 2,711,303 | 6,584,593 | 13,556,515 | 32,922,965 | 46,092,151 | 230,460,755 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -387,329 | -1,936,645 | -2,711,303 | -6,584,593 | -13,556,515 | -32,922,965 | -46,092,151 | -230,460,755 |
