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 104,551,205, 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 | 104,551,205 | |
| -1 | -104,551,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,551,205.
Example:
1 x 104,551,205 = 104,551,205
and
-1 x -104,551,205 = 104,551,205
Notice both answers equal 104,551,205
With that explanation out of the way, let's continue. Next, we take the number 104,551,205 and divide it by 2:
104,551,205 ÷ 2 = 52,275,602.5
If the quotient is a whole number, then 2 and 52,275,602.5 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 | 104,551,205 | |
| -1 | -104,551,205 |
Now, we try dividing 104,551,205 by 3:
104,551,205 ÷ 3 = 34,850,401.6667
If the quotient is a whole number, then 3 and 34,850,401.6667 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 | 104,551,205 | |
| -1 | -104,551,205 |
Let's try dividing by 4:
104,551,205 ÷ 4 = 26,137,801.25
If the quotient is a whole number, then 4 and 26,137,801.25 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 | 104,551,205 | |
| -1 | 104,551,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 100,049 | 500,245 | 1,100,539 | 1,900,931 | 5,502,695 | 9,504,655 | 20,910,241 | 104,551,205 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -100,049 | -500,245 | -1,100,539 | -1,900,931 | -5,502,695 | -9,504,655 | -20,910,241 | -104,551,205 |
