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 50,102,611, 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 | 50,102,611 | |
| -1 | -50,102,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,102,611.
Example:
1 x 50,102,611 = 50,102,611
and
-1 x -50,102,611 = 50,102,611
Notice both answers equal 50,102,611
With that explanation out of the way, let's continue. Next, we take the number 50,102,611 and divide it by 2:
50,102,611 ÷ 2 = 25,051,305.5
If the quotient is a whole number, then 2 and 25,051,305.5 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 | 50,102,611 | |
| -1 | -50,102,611 |
Now, we try dividing 50,102,611 by 3:
50,102,611 ÷ 3 = 16,700,870.3333
If the quotient is a whole number, then 3 and 16,700,870.3333 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 | 50,102,611 | |
| -1 | -50,102,611 |
Let's try dividing by 4:
50,102,611 ÷ 4 = 12,525,652.75
If the quotient is a whole number, then 4 and 12,525,652.75 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 | 50,102,611 | |
| -1 | 50,102,611 |
If you did it right, you will end up with this table:
| 1 | 13 | 43 | 47 | 559 | 611 | 1,907 | 2,021 | 24,791 | 26,273 | 82,001 | 89,629 | 1,066,013 | 1,165,177 | 3,854,047 | 50,102,611 |
| -1 | -13 | -43 | -47 | -559 | -611 | -1,907 | -2,021 | -24,791 | -26,273 | -82,001 | -89,629 | -1,066,013 | -1,165,177 | -3,854,047 | -50,102,611 |
