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 233,802,911, 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 | 233,802,911 | |
| -1 | -233,802,911 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,802,911.
Example:
1 x 233,802,911 = 233,802,911
and
-1 x -233,802,911 = 233,802,911
Notice both answers equal 233,802,911
With that explanation out of the way, let's continue. Next, we take the number 233,802,911 and divide it by 2:
233,802,911 ÷ 2 = 116,901,455.5
If the quotient is a whole number, then 2 and 116,901,455.5 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 | 233,802,911 | |
| -1 | -233,802,911 |
Now, we try dividing 233,802,911 by 3:
233,802,911 ÷ 3 = 77,934,303.6667
If the quotient is a whole number, then 3 and 77,934,303.6667 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 | 233,802,911 | |
| -1 | -233,802,911 |
Let's try dividing by 4:
233,802,911 ÷ 4 = 58,450,727.75
If the quotient is a whole number, then 4 and 58,450,727.75 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 | 233,802,911 | |
| -1 | 233,802,911 |
If you did it right, you will end up with this table:
| 1 | 43 | 89 | 199 | 307 | 3,827 | 8,557 | 13,201 | 17,711 | 27,323 | 61,093 | 761,573 | 1,174,889 | 2,626,999 | 5,437,277 | 233,802,911 |
| -1 | -43 | -89 | -199 | -307 | -3,827 | -8,557 | -13,201 | -17,711 | -27,323 | -61,093 | -761,573 | -1,174,889 | -2,626,999 | -5,437,277 | -233,802,911 |
