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 233,457,311, 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 | 233,457,311 | |
| -1 | -233,457,311 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 233,457,311.
Example:
1 x 233,457,311 = 233,457,311
and
-1 x -233,457,311 = 233,457,311
Notice both answers equal 233,457,311
With that explanation out of the way, let's continue. Next, we take the number 233,457,311 and divide it by 2:
233,457,311 ÷ 2 = 116,728,655.5
If the quotient is a whole number, then 2 and 116,728,655.5 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 | 233,457,311 | |
| -1 | -233,457,311 |
Now, we try dividing 233,457,311 by 3:
233,457,311 ÷ 3 = 77,819,103.6667
If the quotient is a whole number, then 3 and 77,819,103.6667 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 | 233,457,311 | |
| -1 | -233,457,311 |
Let's try dividing by 4:
233,457,311 ÷ 4 = 58,364,327.75
If the quotient is a whole number, then 4 and 58,364,327.75 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 | 233,457,311 | |
| -1 | 233,457,311 |
If you did it right, you will end up with this table:
| 1 | 17 | 31 | 139 | 527 | 2,363 | 3,187 | 4,309 | 54,179 | 73,253 | 98,797 | 442,993 | 1,679,549 | 7,530,881 | 13,732,783 | 233,457,311 |
| -1 | -17 | -31 | -139 | -527 | -2,363 | -3,187 | -4,309 | -54,179 | -73,253 | -98,797 | -442,993 | -1,679,549 | -7,530,881 | -13,732,783 | -233,457,311 |
