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 50,708,405, 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 | 50,708,405 | |
| -1 | -50,708,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,708,405.
Example:
1 x 50,708,405 = 50,708,405
and
-1 x -50,708,405 = 50,708,405
Notice both answers equal 50,708,405
With that explanation out of the way, let's continue. Next, we take the number 50,708,405 and divide it by 2:
50,708,405 ÷ 2 = 25,354,202.5
If the quotient is a whole number, then 2 and 25,354,202.5 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 | 50,708,405 | |
| -1 | -50,708,405 |
Now, we try dividing 50,708,405 by 3:
50,708,405 ÷ 3 = 16,902,801.6667
If the quotient is a whole number, then 3 and 16,902,801.6667 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 | 50,708,405 | |
| -1 | -50,708,405 |
Let's try dividing by 4:
50,708,405 ÷ 4 = 12,677,101.25
If the quotient is a whole number, then 4 and 12,677,101.25 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 | 50,708,405 | |
| -1 | 50,708,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 31 | 55 | 155 | 341 | 1,705 | 29,741 | 148,705 | 327,151 | 921,971 | 1,635,755 | 4,609,855 | 10,141,681 | 50,708,405 |
| -1 | -5 | -11 | -31 | -55 | -155 | -341 | -1,705 | -29,741 | -148,705 | -327,151 | -921,971 | -1,635,755 | -4,609,855 | -10,141,681 | -50,708,405 |
