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 50,455,013, 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 | 50,455,013 | |
| -1 | -50,455,013 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,455,013.
Example:
1 x 50,455,013 = 50,455,013
and
-1 x -50,455,013 = 50,455,013
Notice both answers equal 50,455,013
With that explanation out of the way, let's continue. Next, we take the number 50,455,013 and divide it by 2:
50,455,013 ÷ 2 = 25,227,506.5
If the quotient is a whole number, then 2 and 25,227,506.5 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 | 50,455,013 | |
| -1 | -50,455,013 |
Now, we try dividing 50,455,013 by 3:
50,455,013 ÷ 3 = 16,818,337.6667
If the quotient is a whole number, then 3 and 16,818,337.6667 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 | 50,455,013 | |
| -1 | -50,455,013 |
Let's try dividing by 4:
50,455,013 ÷ 4 = 12,613,753.25
If the quotient is a whole number, then 4 and 12,613,753.25 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 | 50,455,013 | |
| -1 | 50,455,013 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 37 | 133 | 259 | 703 | 4,921 | 10,253 | 71,771 | 194,807 | 379,361 | 1,363,649 | 2,655,527 | 7,207,859 | 50,455,013 |
| -1 | -7 | -19 | -37 | -133 | -259 | -703 | -4,921 | -10,253 | -71,771 | -194,807 | -379,361 | -1,363,649 | -2,655,527 | -7,207,859 | -50,455,013 |
