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 50,350,055, 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 | 50,350,055 | |
| -1 | -50,350,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,350,055.
Example:
1 x 50,350,055 = 50,350,055
and
-1 x -50,350,055 = 50,350,055
Notice both answers equal 50,350,055
With that explanation out of the way, let's continue. Next, we take the number 50,350,055 and divide it by 2:
50,350,055 ÷ 2 = 25,175,027.5
If the quotient is a whole number, then 2 and 25,175,027.5 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 | 50,350,055 | |
| -1 | -50,350,055 |
Now, we try dividing 50,350,055 by 3:
50,350,055 ÷ 3 = 16,783,351.6667
If the quotient is a whole number, then 3 and 16,783,351.6667 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 | 50,350,055 | |
| -1 | -50,350,055 |
Let's try dividing by 4:
50,350,055 ÷ 4 = 12,587,513.75
If the quotient is a whole number, then 4 and 12,587,513.75 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 | 50,350,055 | |
| -1 | 50,350,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 223 | 1,115 | 1,561 | 6,451 | 7,805 | 32,255 | 45,157 | 225,785 | 1,438,573 | 7,192,865 | 10,070,011 | 50,350,055 |
| -1 | -5 | -7 | -35 | -223 | -1,115 | -1,561 | -6,451 | -7,805 | -32,255 | -45,157 | -225,785 | -1,438,573 | -7,192,865 | -10,070,011 | -50,350,055 |
