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 230,104,273, 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 | 230,104,273 | |
| -1 | -230,104,273 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 230,104,273.
Example:
1 x 230,104,273 = 230,104,273
and
-1 x -230,104,273 = 230,104,273
Notice both answers equal 230,104,273
With that explanation out of the way, let's continue. Next, we take the number 230,104,273 and divide it by 2:
230,104,273 ÷ 2 = 115,052,136.5
If the quotient is a whole number, then 2 and 115,052,136.5 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 | 230,104,273 | |
| -1 | -230,104,273 |
Now, we try dividing 230,104,273 by 3:
230,104,273 ÷ 3 = 76,701,424.3333
If the quotient is a whole number, then 3 and 76,701,424.3333 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 | 230,104,273 | |
| -1 | -230,104,273 |
Let's try dividing by 4:
230,104,273 ÷ 4 = 57,526,068.25
If the quotient is a whole number, then 4 and 57,526,068.25 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 | 230,104,273 | |
| -1 | 230,104,273 |
If you did it right, you will end up with this table:
| 1 | 7 | 97 | 113 | 679 | 791 | 2,999 | 10,961 | 20,993 | 76,727 | 290,903 | 338,887 | 2,036,321 | 2,372,209 | 32,872,039 | 230,104,273 |
| -1 | -7 | -97 | -113 | -679 | -791 | -2,999 | -10,961 | -20,993 | -76,727 | -290,903 | -338,887 | -2,036,321 | -2,372,209 | -32,872,039 | -230,104,273 |
