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 230,365,375, 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 | 230,365,375 | |
| -1 | -230,365,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,365,375.
Example:
1 x 230,365,375 = 230,365,375
and
-1 x -230,365,375 = 230,365,375
Notice both answers equal 230,365,375
With that explanation out of the way, let's continue. Next, we take the number 230,365,375 and divide it by 2:
230,365,375 ÷ 2 = 115,182,687.5
If the quotient is a whole number, then 2 and 115,182,687.5 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 | 230,365,375 | |
| -1 | -230,365,375 |
Now, we try dividing 230,365,375 by 3:
230,365,375 ÷ 3 = 76,788,458.3333
If the quotient is a whole number, then 3 and 76,788,458.3333 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 | 230,365,375 | |
| -1 | -230,365,375 |
Let's try dividing by 4:
230,365,375 ÷ 4 = 57,591,343.75
If the quotient is a whole number, then 4 and 57,591,343.75 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 | 230,365,375 | |
| -1 | 230,365,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 89 | 125 | 445 | 2,225 | 11,125 | 20,707 | 103,535 | 517,675 | 1,842,923 | 2,588,375 | 9,214,615 | 46,073,075 | 230,365,375 |
| -1 | -5 | -25 | -89 | -125 | -445 | -2,225 | -11,125 | -20,707 | -103,535 | -517,675 | -1,842,923 | -2,588,375 | -9,214,615 | -46,073,075 | -230,365,375 |
