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 233,222,015, 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 | 233,222,015 | |
| -1 | -233,222,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,222,015.
Example:
1 x 233,222,015 = 233,222,015
and
-1 x -233,222,015 = 233,222,015
Notice both answers equal 233,222,015
With that explanation out of the way, let's continue. Next, we take the number 233,222,015 and divide it by 2:
233,222,015 ÷ 2 = 116,611,007.5
If the quotient is a whole number, then 2 and 116,611,007.5 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 | 233,222,015 | |
| -1 | -233,222,015 |
Now, we try dividing 233,222,015 by 3:
233,222,015 ÷ 3 = 77,740,671.6667
If the quotient is a whole number, then 3 and 77,740,671.6667 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 | 233,222,015 | |
| -1 | -233,222,015 |
Let's try dividing by 4:
233,222,015 ÷ 4 = 58,305,503.75
If the quotient is a whole number, then 4 and 58,305,503.75 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 | 233,222,015 | |
| -1 | 233,222,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 107 | 535 | 1,391 | 6,955 | 33,533 | 167,665 | 435,929 | 2,179,645 | 3,588,031 | 17,940,155 | 46,644,403 | 233,222,015 |
| -1 | -5 | -13 | -65 | -107 | -535 | -1,391 | -6,955 | -33,533 | -167,665 | -435,929 | -2,179,645 | -3,588,031 | -17,940,155 | -46,644,403 | -233,222,015 |
