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 50,707,405, 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 | 50,707,405 | |
| -1 | -50,707,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,707,405.
Example:
1 x 50,707,405 = 50,707,405
and
-1 x -50,707,405 = 50,707,405
Notice both answers equal 50,707,405
With that explanation out of the way, let's continue. Next, we take the number 50,707,405 and divide it by 2:
50,707,405 ÷ 2 = 25,353,702.5
If the quotient is a whole number, then 2 and 25,353,702.5 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 | 50,707,405 | |
| -1 | -50,707,405 |
Now, we try dividing 50,707,405 by 3:
50,707,405 ÷ 3 = 16,902,468.3333
If the quotient is a whole number, then 3 and 16,902,468.3333 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 | 50,707,405 | |
| -1 | -50,707,405 |
Let's try dividing by 4:
50,707,405 ÷ 4 = 12,676,851.25
If the quotient is a whole number, then 4 and 12,676,851.25 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 | 50,707,405 | |
| -1 | 50,707,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 245 | 343 | 1,715 | 29,567 | 147,835 | 206,969 | 1,034,845 | 1,448,783 | 7,243,915 | 10,141,481 | 50,707,405 |
| -1 | -5 | -7 | -35 | -49 | -245 | -343 | -1,715 | -29,567 | -147,835 | -206,969 | -1,034,845 | -1,448,783 | -7,243,915 | -10,141,481 | -50,707,405 |
