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 243,333,223, 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 | 243,333,223 | |
| -1 | -243,333,223 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 243,333,223.
Example:
1 x 243,333,223 = 243,333,223
and
-1 x -243,333,223 = 243,333,223
Notice both answers equal 243,333,223
With that explanation out of the way, let's continue. Next, we take the number 243,333,223 and divide it by 2:
243,333,223 ÷ 2 = 121,666,611.5
If the quotient is a whole number, then 2 and 121,666,611.5 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 | 243,333,223 | |
| -1 | -243,333,223 |
Now, we try dividing 243,333,223 by 3:
243,333,223 ÷ 3 = 81,111,074.3333
If the quotient is a whole number, then 3 and 81,111,074.3333 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 | 243,333,223 | |
| -1 | -243,333,223 |
Let's try dividing by 4:
243,333,223 ÷ 4 = 60,833,305.75
If the quotient is a whole number, then 4 and 60,833,305.75 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 | 243,333,223 | |
| -1 | 243,333,223 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 701 | 2,917 | 4,907 | 11,917 | 20,419 | 49,589 | 83,419 | 347,123 | 2,044,817 | 14,313,719 | 34,761,889 | 243,333,223 |
| -1 | -7 | -17 | -119 | -701 | -2,917 | -4,907 | -11,917 | -20,419 | -49,589 | -83,419 | -347,123 | -2,044,817 | -14,313,719 | -34,761,889 | -243,333,223 |
