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 50,510,555, 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 | 50,510,555 | |
| -1 | -50,510,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,510,555.
Example:
1 x 50,510,555 = 50,510,555
and
-1 x -50,510,555 = 50,510,555
Notice both answers equal 50,510,555
With that explanation out of the way, let's continue. Next, we take the number 50,510,555 and divide it by 2:
50,510,555 ÷ 2 = 25,255,277.5
If the quotient is a whole number, then 2 and 25,255,277.5 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 | 50,510,555 | |
| -1 | -50,510,555 |
Now, we try dividing 50,510,555 by 3:
50,510,555 ÷ 3 = 16,836,851.6667
If the quotient is a whole number, then 3 and 16,836,851.6667 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 | 50,510,555 | |
| -1 | -50,510,555 |
Let's try dividing by 4:
50,510,555 ÷ 4 = 12,627,638.75
If the quotient is a whole number, then 4 and 12,627,638.75 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 | 50,510,555 | |
| -1 | 50,510,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 701 | 3,505 | 14,411 | 72,055 | 10,102,111 | 50,510,555 |
| -1 | -5 | -701 | -3,505 | -14,411 | -72,055 | -10,102,111 | -50,510,555 |
