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 234,236,665, 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 | 234,236,665 | |
| -1 | -234,236,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 234,236,665.
Example:
1 x 234,236,665 = 234,236,665
and
-1 x -234,236,665 = 234,236,665
Notice both answers equal 234,236,665
With that explanation out of the way, let's continue. Next, we take the number 234,236,665 and divide it by 2:
234,236,665 ÷ 2 = 117,118,332.5
If the quotient is a whole number, then 2 and 117,118,332.5 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 | 234,236,665 | |
| -1 | -234,236,665 |
Now, we try dividing 234,236,665 by 3:
234,236,665 ÷ 3 = 78,078,888.3333
If the quotient is a whole number, then 3 and 78,078,888.3333 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 | 234,236,665 | |
| -1 | -234,236,665 |
Let's try dividing by 4:
234,236,665 ÷ 4 = 58,559,166.25
If the quotient is a whole number, then 4 and 58,559,166.25 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 | 234,236,665 | |
| -1 | 234,236,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 631 | 3,155 | 5,711 | 8,203 | 28,555 | 41,015 | 74,243 | 371,215 | 3,603,641 | 18,018,205 | 46,847,333 | 234,236,665 |
| -1 | -5 | -13 | -65 | -631 | -3,155 | -5,711 | -8,203 | -28,555 | -41,015 | -74,243 | -371,215 | -3,603,641 | -18,018,205 | -46,847,333 | -234,236,665 |
