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 50,538,085, 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 | 50,538,085 | |
| -1 | -50,538,085 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,538,085.
Example:
1 x 50,538,085 = 50,538,085
and
-1 x -50,538,085 = 50,538,085
Notice both answers equal 50,538,085
With that explanation out of the way, let's continue. Next, we take the number 50,538,085 and divide it by 2:
50,538,085 ÷ 2 = 25,269,042.5
If the quotient is a whole number, then 2 and 25,269,042.5 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 | 50,538,085 | |
| -1 | -50,538,085 |
Now, we try dividing 50,538,085 by 3:
50,538,085 ÷ 3 = 16,846,028.3333
If the quotient is a whole number, then 3 and 16,846,028.3333 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 | 50,538,085 | |
| -1 | -50,538,085 |
Let's try dividing by 4:
50,538,085 ÷ 4 = 12,634,521.25
If the quotient is a whole number, then 4 and 12,634,521.25 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 | 50,538,085 | |
| -1 | 50,538,085 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 409 | 1,901 | 2,045 | 5,317 | 9,505 | 24,713 | 26,585 | 123,565 | 777,509 | 3,887,545 | 10,107,617 | 50,538,085 |
| -1 | -5 | -13 | -65 | -409 | -1,901 | -2,045 | -5,317 | -9,505 | -24,713 | -26,585 | -123,565 | -777,509 | -3,887,545 | -10,107,617 | -50,538,085 |
