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 231,233,303, 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 | 231,233,303 | |
| -1 | -231,233,303 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,233,303.
Example:
1 x 231,233,303 = 231,233,303
and
-1 x -231,233,303 = 231,233,303
Notice both answers equal 231,233,303
With that explanation out of the way, let's continue. Next, we take the number 231,233,303 and divide it by 2:
231,233,303 ÷ 2 = 115,616,651.5
If the quotient is a whole number, then 2 and 115,616,651.5 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 | 231,233,303 | |
| -1 | -231,233,303 |
Now, we try dividing 231,233,303 by 3:
231,233,303 ÷ 3 = 77,077,767.6667
If the quotient is a whole number, then 3 and 77,077,767.6667 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 | 231,233,303 | |
| -1 | -231,233,303 |
Let's try dividing by 4:
231,233,303 ÷ 4 = 57,808,325.75
If the quotient is a whole number, then 4 and 57,808,325.75 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 | 231,233,303 | |
| -1 | 231,233,303 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 89 | 119 | 623 | 833 | 1,513 | 3,119 | 4,361 | 10,591 | 21,833 | 53,023 | 74,137 | 152,831 | 277,591 | 371,161 | 1,943,137 | 2,598,127 | 4,719,047 | 13,601,959 | 33,033,329 | 231,233,303 |
| -1 | -7 | -17 | -49 | -89 | -119 | -623 | -833 | -1,513 | -3,119 | -4,361 | -10,591 | -21,833 | -53,023 | -74,137 | -152,831 | -277,591 | -371,161 | -1,943,137 | -2,598,127 | -4,719,047 | -13,601,959 | -33,033,329 | -231,233,303 |
