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 50,315,551, 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 | 50,315,551 | |
| -1 | -50,315,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,315,551.
Example:
1 x 50,315,551 = 50,315,551
and
-1 x -50,315,551 = 50,315,551
Notice both answers equal 50,315,551
With that explanation out of the way, let's continue. Next, we take the number 50,315,551 and divide it by 2:
50,315,551 ÷ 2 = 25,157,775.5
If the quotient is a whole number, then 2 and 25,157,775.5 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 | 50,315,551 | |
| -1 | -50,315,551 |
Now, we try dividing 50,315,551 by 3:
50,315,551 ÷ 3 = 16,771,850.3333
If the quotient is a whole number, then 3 and 16,771,850.3333 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 | 50,315,551 | |
| -1 | -50,315,551 |
Let's try dividing by 4:
50,315,551 ÷ 4 = 12,578,887.75
If the quotient is a whole number, then 4 and 12,578,887.75 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 | 50,315,551 | |
| -1 | 50,315,551 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 29 | 121 | 143 | 319 | 377 | 1,103 | 1,573 | 3,509 | 4,147 | 12,133 | 14,339 | 31,987 | 45,617 | 133,463 | 157,729 | 351,857 | 415,831 | 1,735,019 | 3,870,427 | 4,574,141 | 50,315,551 |
| -1 | -11 | -13 | -29 | -121 | -143 | -319 | -377 | -1,103 | -1,573 | -3,509 | -4,147 | -12,133 | -14,339 | -31,987 | -45,617 | -133,463 | -157,729 | -351,857 | -415,831 | -1,735,019 | -3,870,427 | -4,574,141 | -50,315,551 |
