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 233,665,165, 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 | 233,665,165 | |
| -1 | -233,665,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,665,165.
Example:
1 x 233,665,165 = 233,665,165
and
-1 x -233,665,165 = 233,665,165
Notice both answers equal 233,665,165
With that explanation out of the way, let's continue. Next, we take the number 233,665,165 and divide it by 2:
233,665,165 ÷ 2 = 116,832,582.5
If the quotient is a whole number, then 2 and 116,832,582.5 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 | 233,665,165 | |
| -1 | -233,665,165 |
Now, we try dividing 233,665,165 by 3:
233,665,165 ÷ 3 = 77,888,388.3333
If the quotient is a whole number, then 3 and 77,888,388.3333 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 | 233,665,165 | |
| -1 | -233,665,165 |
Let's try dividing by 4:
233,665,165 ÷ 4 = 58,416,291.25
If the quotient is a whole number, then 4 and 58,416,291.25 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 | 233,665,165 | |
| -1 | 233,665,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 241 | 1,205 | 5,543 | 8,431 | 27,715 | 42,155 | 193,913 | 969,565 | 2,031,871 | 10,159,355 | 46,733,033 | 233,665,165 |
| -1 | -5 | -23 | -115 | -241 | -1,205 | -5,543 | -8,431 | -27,715 | -42,155 | -193,913 | -969,565 | -2,031,871 | -10,159,355 | -46,733,033 | -233,665,165 |
