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 223,064,231, 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 | 223,064,231 | |
| -1 | -223,064,231 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 223,064,231.
Example:
1 x 223,064,231 = 223,064,231
and
-1 x -223,064,231 = 223,064,231
Notice both answers equal 223,064,231
With that explanation out of the way, let's continue. Next, we take the number 223,064,231 and divide it by 2:
223,064,231 ÷ 2 = 111,532,115.5
If the quotient is a whole number, then 2 and 111,532,115.5 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 | 223,064,231 | |
| -1 | -223,064,231 |
Now, we try dividing 223,064,231 by 3:
223,064,231 ÷ 3 = 74,354,743.6667
If the quotient is a whole number, then 3 and 74,354,743.6667 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 | 223,064,231 | |
| -1 | -223,064,231 |
Let's try dividing by 4:
223,064,231 ÷ 4 = 55,766,057.75
If the quotient is a whole number, then 4 and 55,766,057.75 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 | 223,064,231 | |
| -1 | 223,064,231 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 41 | 481 | 533 | 1,517 | 11,311 | 19,721 | 147,043 | 418,507 | 463,751 | 5,440,591 | 6,028,763 | 17,158,787 | 223,064,231 |
| -1 | -13 | -37 | -41 | -481 | -533 | -1,517 | -11,311 | -19,721 | -147,043 | -418,507 | -463,751 | -5,440,591 | -6,028,763 | -17,158,787 | -223,064,231 |
