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 232,212,305, 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 | 232,212,305 | |
| -1 | -232,212,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 232,212,305.
Example:
1 x 232,212,305 = 232,212,305
and
-1 x -232,212,305 = 232,212,305
Notice both answers equal 232,212,305
With that explanation out of the way, let's continue. Next, we take the number 232,212,305 and divide it by 2:
232,212,305 ÷ 2 = 116,106,152.5
If the quotient is a whole number, then 2 and 116,106,152.5 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 | 232,212,305 | |
| -1 | -232,212,305 |
Now, we try dividing 232,212,305 by 3:
232,212,305 ÷ 3 = 77,404,101.6667
If the quotient is a whole number, then 3 and 77,404,101.6667 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 | 232,212,305 | |
| -1 | -232,212,305 |
Let's try dividing by 4:
232,212,305 ÷ 4 = 58,053,076.25
If the quotient is a whole number, then 4 and 58,053,076.25 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 | 232,212,305 | |
| -1 | 232,212,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 521 | 2,605 | 6,773 | 6,857 | 33,865 | 34,285 | 89,141 | 445,705 | 3,572,497 | 17,862,485 | 46,442,461 | 232,212,305 |
| -1 | -5 | -13 | -65 | -521 | -2,605 | -6,773 | -6,857 | -33,865 | -34,285 | -89,141 | -445,705 | -3,572,497 | -17,862,485 | -46,442,461 | -232,212,305 |
