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 231,652,237, 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 | 231,652,237 | |
| -1 | -231,652,237 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,652,237.
Example:
1 x 231,652,237 = 231,652,237
and
-1 x -231,652,237 = 231,652,237
Notice both answers equal 231,652,237
With that explanation out of the way, let's continue. Next, we take the number 231,652,237 and divide it by 2:
231,652,237 ÷ 2 = 115,826,118.5
If the quotient is a whole number, then 2 and 115,826,118.5 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 | 231,652,237 | |
| -1 | -231,652,237 |
Now, we try dividing 231,652,237 by 3:
231,652,237 ÷ 3 = 77,217,412.3333
If the quotient is a whole number, then 3 and 77,217,412.3333 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 | 231,652,237 | |
| -1 | -231,652,237 |
Let's try dividing by 4:
231,652,237 ÷ 4 = 57,913,059.25
If the quotient is a whole number, then 4 and 57,913,059.25 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 | 231,652,237 | |
| -1 | 231,652,237 |
If you did it right, you will end up with this table:
| 1 | 19 | 47 | 149 | 893 | 1,741 | 2,831 | 7,003 | 33,079 | 81,827 | 133,057 | 259,409 | 1,554,713 | 4,928,771 | 12,192,223 | 231,652,237 |
| -1 | -19 | -47 | -149 | -893 | -1,741 | -2,831 | -7,003 | -33,079 | -81,827 | -133,057 | -259,409 | -1,554,713 | -4,928,771 | -12,192,223 | -231,652,237 |
