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 50,355,361, 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 | 50,355,361 | |
| -1 | -50,355,361 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,355,361.
Example:
1 x 50,355,361 = 50,355,361
and
-1 x -50,355,361 = 50,355,361
Notice both answers equal 50,355,361
With that explanation out of the way, let's continue. Next, we take the number 50,355,361 and divide it by 2:
50,355,361 ÷ 2 = 25,177,680.5
If the quotient is a whole number, then 2 and 25,177,680.5 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 | 50,355,361 | |
| -1 | -50,355,361 |
Now, we try dividing 50,355,361 by 3:
50,355,361 ÷ 3 = 16,785,120.3333
If the quotient is a whole number, then 3 and 16,785,120.3333 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 | 50,355,361 | |
| -1 | -50,355,361 |
Let's try dividing by 4:
50,355,361 ÷ 4 = 12,588,840.25
If the quotient is a whole number, then 4 and 12,588,840.25 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 | 50,355,361 | |
| -1 | 50,355,361 |
If you did it right, you will end up with this table:
| 1 | 7 | 103 | 211 | 331 | 721 | 1,477 | 2,317 | 21,733 | 34,093 | 69,841 | 152,131 | 238,651 | 488,887 | 7,193,623 | 50,355,361 |
| -1 | -7 | -103 | -211 | -331 | -721 | -1,477 | -2,317 | -21,733 | -34,093 | -69,841 | -152,131 | -238,651 | -488,887 | -7,193,623 | -50,355,361 |
