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 231,130,243, 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 | 231,130,243 | |
| -1 | -231,130,243 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,130,243.
Example:
1 x 231,130,243 = 231,130,243
and
-1 x -231,130,243 = 231,130,243
Notice both answers equal 231,130,243
With that explanation out of the way, let's continue. Next, we take the number 231,130,243 and divide it by 2:
231,130,243 ÷ 2 = 115,565,121.5
If the quotient is a whole number, then 2 and 115,565,121.5 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 | 231,130,243 | |
| -1 | -231,130,243 |
Now, we try dividing 231,130,243 by 3:
231,130,243 ÷ 3 = 77,043,414.3333
If the quotient is a whole number, then 3 and 77,043,414.3333 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 | 231,130,243 | |
| -1 | -231,130,243 |
Let's try dividing by 4:
231,130,243 ÷ 4 = 57,782,560.75
If the quotient is a whole number, then 4 and 57,782,560.75 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 | 231,130,243 | |
| -1 | 231,130,243 |
If you did it right, you will end up with this table:
| 1 | 23 | 41 | 131 | 943 | 1,871 | 3,013 | 5,371 | 43,033 | 76,711 | 123,533 | 245,101 | 1,764,353 | 5,637,323 | 10,049,141 | 231,130,243 |
| -1 | -23 | -41 | -131 | -943 | -1,871 | -3,013 | -5,371 | -43,033 | -76,711 | -123,533 | -245,101 | -1,764,353 | -5,637,323 | -10,049,141 | -231,130,243 |
