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 50,512,555, 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 | 50,512,555 | |
| -1 | -50,512,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,512,555.
Example:
1 x 50,512,555 = 50,512,555
and
-1 x -50,512,555 = 50,512,555
Notice both answers equal 50,512,555
With that explanation out of the way, let's continue. Next, we take the number 50,512,555 and divide it by 2:
50,512,555 ÷ 2 = 25,256,277.5
If the quotient is a whole number, then 2 and 25,256,277.5 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 | 50,512,555 | |
| -1 | -50,512,555 |
Now, we try dividing 50,512,555 by 3:
50,512,555 ÷ 3 = 16,837,518.3333
If the quotient is a whole number, then 3 and 16,837,518.3333 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 | 50,512,555 | |
| -1 | -50,512,555 |
Let's try dividing by 4:
50,512,555 ÷ 4 = 12,628,138.75
If the quotient is a whole number, then 4 and 12,628,138.75 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 | 50,512,555 | |
| -1 | 50,512,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 83 | 295 | 415 | 2,063 | 4,897 | 10,315 | 24,485 | 121,717 | 171,229 | 608,585 | 856,145 | 10,102,511 | 50,512,555 |
| -1 | -5 | -59 | -83 | -295 | -415 | -2,063 | -4,897 | -10,315 | -24,485 | -121,717 | -171,229 | -608,585 | -856,145 | -10,102,511 | -50,512,555 |
