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 50,200,073, 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 | 50,200,073 | |
| -1 | -50,200,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,200,073.
Example:
1 x 50,200,073 = 50,200,073
and
-1 x -50,200,073 = 50,200,073
Notice both answers equal 50,200,073
With that explanation out of the way, let's continue. Next, we take the number 50,200,073 and divide it by 2:
50,200,073 ÷ 2 = 25,100,036.5
If the quotient is a whole number, then 2 and 25,100,036.5 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 | 50,200,073 | |
| -1 | -50,200,073 |
Now, we try dividing 50,200,073 by 3:
50,200,073 ÷ 3 = 16,733,357.6667
If the quotient is a whole number, then 3 and 16,733,357.6667 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 | 50,200,073 | |
| -1 | -50,200,073 |
Let's try dividing by 4:
50,200,073 ÷ 4 = 12,550,018.25
If the quotient is a whole number, then 4 and 12,550,018.25 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 | 50,200,073 | |
| -1 | 50,200,073 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 29 | 77 | 203 | 319 | 2,233 | 22,481 | 157,367 | 247,291 | 651,949 | 1,731,037 | 4,563,643 | 7,171,439 | 50,200,073 |
| -1 | -7 | -11 | -29 | -77 | -203 | -319 | -2,233 | -22,481 | -157,367 | -247,291 | -651,949 | -1,731,037 | -4,563,643 | -7,171,439 | -50,200,073 |
