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 231,232,235, 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 | 231,232,235 | |
| -1 | -231,232,235 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,232,235.
Example:
1 x 231,232,235 = 231,232,235
and
-1 x -231,232,235 = 231,232,235
Notice both answers equal 231,232,235
With that explanation out of the way, let's continue. Next, we take the number 231,232,235 and divide it by 2:
231,232,235 ÷ 2 = 115,616,117.5
If the quotient is a whole number, then 2 and 115,616,117.5 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 | 231,232,235 | |
| -1 | -231,232,235 |
Now, we try dividing 231,232,235 by 3:
231,232,235 ÷ 3 = 77,077,411.6667
If the quotient is a whole number, then 3 and 77,077,411.6667 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 | 231,232,235 | |
| -1 | -231,232,235 |
Let's try dividing by 4:
231,232,235 ÷ 4 = 57,808,058.75
If the quotient is a whole number, then 4 and 57,808,058.75 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 | 231,232,235 | |
| -1 | 231,232,235 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 89 | 445 | 1,157 | 5,785 | 39,971 | 199,855 | 519,623 | 2,598,115 | 3,557,419 | 17,787,095 | 46,246,447 | 231,232,235 |
| -1 | -5 | -13 | -65 | -89 | -445 | -1,157 | -5,785 | -39,971 | -199,855 | -519,623 | -2,598,115 | -3,557,419 | -17,787,095 | -46,246,447 | -231,232,235 |
