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 233,472,245, 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 | 233,472,245 | |
| -1 | -233,472,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,472,245.
Example:
1 x 233,472,245 = 233,472,245
and
-1 x -233,472,245 = 233,472,245
Notice both answers equal 233,472,245
With that explanation out of the way, let's continue. Next, we take the number 233,472,245 and divide it by 2:
233,472,245 ÷ 2 = 116,736,122.5
If the quotient is a whole number, then 2 and 116,736,122.5 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 | 233,472,245 | |
| -1 | -233,472,245 |
Now, we try dividing 233,472,245 by 3:
233,472,245 ÷ 3 = 77,824,081.6667
If the quotient is a whole number, then 3 and 77,824,081.6667 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 | 233,472,245 | |
| -1 | -233,472,245 |
Let's try dividing by 4:
233,472,245 ÷ 4 = 58,368,061.25
If the quotient is a whole number, then 4 and 58,368,061.25 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 | 233,472,245 | |
| -1 | 233,472,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 41 | 205 | 769 | 1,481 | 3,845 | 7,405 | 31,529 | 60,721 | 157,645 | 303,605 | 1,138,889 | 5,694,445 | 46,694,449 | 233,472,245 |
| -1 | -5 | -41 | -205 | -769 | -1,481 | -3,845 | -7,405 | -31,529 | -60,721 | -157,645 | -303,605 | -1,138,889 | -5,694,445 | -46,694,449 | -233,472,245 |
