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 225,344,123, 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 | 225,344,123 | |
| -1 | -225,344,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 225,344,123.
Example:
1 x 225,344,123 = 225,344,123
and
-1 x -225,344,123 = 225,344,123
Notice both answers equal 225,344,123
With that explanation out of the way, let's continue. Next, we take the number 225,344,123 and divide it by 2:
225,344,123 ÷ 2 = 112,672,061.5
If the quotient is a whole number, then 2 and 112,672,061.5 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 | 225,344,123 | |
| -1 | -225,344,123 |
Now, we try dividing 225,344,123 by 3:
225,344,123 ÷ 3 = 75,114,707.6667
If the quotient is a whole number, then 3 and 75,114,707.6667 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 | 225,344,123 | |
| -1 | -225,344,123 |
Let's try dividing by 4:
225,344,123 ÷ 4 = 56,336,030.75
If the quotient is a whole number, then 4 and 56,336,030.75 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 | 225,344,123 | |
| -1 | 225,344,123 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 43 | 551 | 817 | 1,247 | 9,511 | 23,693 | 180,709 | 275,819 | 408,973 | 5,240,561 | 7,770,487 | 11,860,217 | 225,344,123 |
| -1 | -19 | -29 | -43 | -551 | -817 | -1,247 | -9,511 | -23,693 | -180,709 | -275,819 | -408,973 | -5,240,561 | -7,770,487 | -11,860,217 | -225,344,123 |
