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 163,231,343, 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 | 163,231,343 | |
| -1 | -163,231,343 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 163,231,343.
Example:
1 x 163,231,343 = 163,231,343
and
-1 x -163,231,343 = 163,231,343
Notice both answers equal 163,231,343
With that explanation out of the way, let's continue. Next, we take the number 163,231,343 and divide it by 2:
163,231,343 ÷ 2 = 81,615,671.5
If the quotient is a whole number, then 2 and 81,615,671.5 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 | 163,231,343 | |
| -1 | -163,231,343 |
Now, we try dividing 163,231,343 by 3:
163,231,343 ÷ 3 = 54,410,447.6667
If the quotient is a whole number, then 3 and 54,410,447.6667 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 | 163,231,343 | |
| -1 | -163,231,343 |
Let's try dividing by 4:
163,231,343 ÷ 4 = 40,807,835.75
If the quotient is a whole number, then 4 and 40,807,835.75 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 | 163,231,343 | |
| -1 | 163,231,343 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 71 | 319 | 781 | 2,059 | 7,207 | 22,649 | 79,277 | 209,003 | 511,697 | 2,299,033 | 5,628,667 | 14,839,213 | 163,231,343 |
| -1 | -11 | -29 | -71 | -319 | -781 | -2,059 | -7,207 | -22,649 | -79,277 | -209,003 | -511,697 | -2,299,033 | -5,628,667 | -14,839,213 | -163,231,343 |
