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 50,213,117, 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 | 50,213,117 | |
| -1 | -50,213,117 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,213,117.
Example:
1 x 50,213,117 = 50,213,117
and
-1 x -50,213,117 = 50,213,117
Notice both answers equal 50,213,117
With that explanation out of the way, let's continue. Next, we take the number 50,213,117 and divide it by 2:
50,213,117 ÷ 2 = 25,106,558.5
If the quotient is a whole number, then 2 and 25,106,558.5 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 | 50,213,117 | |
| -1 | -50,213,117 |
Now, we try dividing 50,213,117 by 3:
50,213,117 ÷ 3 = 16,737,705.6667
If the quotient is a whole number, then 3 and 16,737,705.6667 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 | 50,213,117 | |
| -1 | -50,213,117 |
Let's try dividing by 4:
50,213,117 ÷ 4 = 12,553,279.25
If the quotient is a whole number, then 4 and 12,553,279.25 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 | 50,213,117 | |
| -1 | 50,213,117 |
If you did it right, you will end up with this table:
| 1 | 23 | 71 | 97 | 317 | 1,633 | 2,231 | 6,887 | 7,291 | 22,507 | 30,749 | 158,401 | 517,661 | 707,227 | 2,183,179 | 50,213,117 |
| -1 | -23 | -71 | -97 | -317 | -1,633 | -2,231 | -6,887 | -7,291 | -22,507 | -30,749 | -158,401 | -517,661 | -707,227 | -2,183,179 | -50,213,117 |
