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 50,502,751, 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 | 50,502,751 | |
| -1 | -50,502,751 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,502,751.
Example:
1 x 50,502,751 = 50,502,751
and
-1 x -50,502,751 = 50,502,751
Notice both answers equal 50,502,751
With that explanation out of the way, let's continue. Next, we take the number 50,502,751 and divide it by 2:
50,502,751 ÷ 2 = 25,251,375.5
If the quotient is a whole number, then 2 and 25,251,375.5 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 | 50,502,751 | |
| -1 | -50,502,751 |
Now, we try dividing 50,502,751 by 3:
50,502,751 ÷ 3 = 16,834,250.3333
If the quotient is a whole number, then 3 and 16,834,250.3333 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 | 50,502,751 | |
| -1 | -50,502,751 |
Let's try dividing by 4:
50,502,751 ÷ 4 = 12,625,687.75
If the quotient is a whole number, then 4 and 12,625,687.75 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 | 50,502,751 | |
| -1 | 50,502,751 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 113 | 403 | 1,109 | 1,469 | 3,503 | 14,417 | 34,379 | 45,539 | 125,317 | 446,927 | 1,629,121 | 3,884,827 | 50,502,751 |
| -1 | -13 | -31 | -113 | -403 | -1,109 | -1,469 | -3,503 | -14,417 | -34,379 | -45,539 | -125,317 | -446,927 | -1,629,121 | -3,884,827 | -50,502,751 |
