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 50,357,857, 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 | 50,357,857 | |
| -1 | -50,357,857 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,357,857.
Example:
1 x 50,357,857 = 50,357,857
and
-1 x -50,357,857 = 50,357,857
Notice both answers equal 50,357,857
With that explanation out of the way, let's continue. Next, we take the number 50,357,857 and divide it by 2:
50,357,857 ÷ 2 = 25,178,928.5
If the quotient is a whole number, then 2 and 25,178,928.5 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 | 50,357,857 | |
| -1 | -50,357,857 |
Now, we try dividing 50,357,857 by 3:
50,357,857 ÷ 3 = 16,785,952.3333
If the quotient is a whole number, then 3 and 16,785,952.3333 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 | 50,357,857 | |
| -1 | -50,357,857 |
Let's try dividing by 4:
50,357,857 ÷ 4 = 12,589,464.25
If the quotient is a whole number, then 4 and 12,589,464.25 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 | 50,357,857 | |
| -1 | 50,357,857 |
If you did it right, you will end up with this table:
| 1 | 11 | 31 | 59 | 341 | 649 | 1,829 | 2,503 | 20,119 | 27,533 | 77,593 | 147,677 | 853,523 | 1,624,447 | 4,577,987 | 50,357,857 |
| -1 | -11 | -31 | -59 | -341 | -649 | -1,829 | -2,503 | -20,119 | -27,533 | -77,593 | -147,677 | -853,523 | -1,624,447 | -4,577,987 | -50,357,857 |
