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 50,165,507, 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 | 50,165,507 | |
| -1 | -50,165,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,165,507.
Example:
1 x 50,165,507 = 50,165,507
and
-1 x -50,165,507 = 50,165,507
Notice both answers equal 50,165,507
With that explanation out of the way, let's continue. Next, we take the number 50,165,507 and divide it by 2:
50,165,507 ÷ 2 = 25,082,753.5
If the quotient is a whole number, then 2 and 25,082,753.5 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 | 50,165,507 | |
| -1 | -50,165,507 |
Now, we try dividing 50,165,507 by 3:
50,165,507 ÷ 3 = 16,721,835.6667
If the quotient is a whole number, then 3 and 16,721,835.6667 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 | 50,165,507 | |
| -1 | -50,165,507 |
Let's try dividing by 4:
50,165,507 ÷ 4 = 12,541,376.75
If the quotient is a whole number, then 4 and 12,541,376.75 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 | 50,165,507 | |
| -1 | 50,165,507 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 53 | 161 | 371 | 1,219 | 5,879 | 8,533 | 41,153 | 135,217 | 311,587 | 946,519 | 2,181,109 | 7,166,501 | 50,165,507 |
| -1 | -7 | -23 | -53 | -161 | -371 | -1,219 | -5,879 | -8,533 | -41,153 | -135,217 | -311,587 | -946,519 | -2,181,109 | -7,166,501 | -50,165,507 |
