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 50,056,517, 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 | 50,056,517 | |
| -1 | -50,056,517 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,056,517.
Example:
1 x 50,056,517 = 50,056,517
and
-1 x -50,056,517 = 50,056,517
Notice both answers equal 50,056,517
With that explanation out of the way, let's continue. Next, we take the number 50,056,517 and divide it by 2:
50,056,517 ÷ 2 = 25,028,258.5
If the quotient is a whole number, then 2 and 25,028,258.5 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 | 50,056,517 | |
| -1 | -50,056,517 |
Now, we try dividing 50,056,517 by 3:
50,056,517 ÷ 3 = 16,685,505.6667
If the quotient is a whole number, then 3 and 16,685,505.6667 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 | 50,056,517 | |
| -1 | -50,056,517 |
Let's try dividing by 4:
50,056,517 ÷ 4 = 12,514,129.25
If the quotient is a whole number, then 4 and 12,514,129.25 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 | 50,056,517 | |
| -1 | 50,056,517 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 547 | 769 | 3,829 | 5,383 | 9,299 | 13,073 | 65,093 | 91,511 | 420,643 | 2,944,501 | 7,150,931 | 50,056,517 |
| -1 | -7 | -17 | -119 | -547 | -769 | -3,829 | -5,383 | -9,299 | -13,073 | -65,093 | -91,511 | -420,643 | -2,944,501 | -7,150,931 | -50,056,517 |
