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 230,308,379, 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 | 230,308,379 | |
| -1 | -230,308,379 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,308,379.
Example:
1 x 230,308,379 = 230,308,379
and
-1 x -230,308,379 = 230,308,379
Notice both answers equal 230,308,379
With that explanation out of the way, let's continue. Next, we take the number 230,308,379 and divide it by 2:
230,308,379 ÷ 2 = 115,154,189.5
If the quotient is a whole number, then 2 and 115,154,189.5 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 | 230,308,379 | |
| -1 | -230,308,379 |
Now, we try dividing 230,308,379 by 3:
230,308,379 ÷ 3 = 76,769,459.6667
If the quotient is a whole number, then 3 and 76,769,459.6667 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 | 230,308,379 | |
| -1 | -230,308,379 |
Let's try dividing by 4:
230,308,379 ÷ 4 = 57,577,094.75
If the quotient is a whole number, then 4 and 57,577,094.75 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 | 230,308,379 | |
| -1 | 230,308,379 |
If you did it right, you will end up with this table:
| 1 | 7 | 49 | 223 | 343 | 1,561 | 3,011 | 10,927 | 21,077 | 76,489 | 147,539 | 671,453 | 1,032,773 | 4,700,171 | 32,901,197 | 230,308,379 |
| -1 | -7 | -49 | -223 | -343 | -1,561 | -3,011 | -10,927 | -21,077 | -76,489 | -147,539 | -671,453 | -1,032,773 | -4,700,171 | -32,901,197 | -230,308,379 |
