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 204,450,467, 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 | 204,450,467 | |
| -1 | -204,450,467 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 204,450,467.
Example:
1 x 204,450,467 = 204,450,467
and
-1 x -204,450,467 = 204,450,467
Notice both answers equal 204,450,467
With that explanation out of the way, let's continue. Next, we take the number 204,450,467 and divide it by 2:
204,450,467 ÷ 2 = 102,225,233.5
If the quotient is a whole number, then 2 and 102,225,233.5 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 | 204,450,467 | |
| -1 | -204,450,467 |
Now, we try dividing 204,450,467 by 3:
204,450,467 ÷ 3 = 68,150,155.6667
If the quotient is a whole number, then 3 and 68,150,155.6667 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 | 204,450,467 | |
| -1 | -204,450,467 |
Let's try dividing by 4:
204,450,467 ÷ 4 = 51,112,616.75
If the quotient is a whole number, then 4 and 51,112,616.75 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 | 204,450,467 | |
| -1 | 204,450,467 |
If you did it right, you will end up with this table:
| 1 | 13 | 61 | 311 | 793 | 829 | 4,043 | 10,777 | 18,971 | 50,569 | 246,623 | 257,819 | 657,397 | 3,351,647 | 15,726,959 | 204,450,467 |
| -1 | -13 | -61 | -311 | -793 | -829 | -4,043 | -10,777 | -18,971 | -50,569 | -246,623 | -257,819 | -657,397 | -3,351,647 | -15,726,959 | -204,450,467 |
