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 50,416,457, 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 | 50,416,457 | |
| -1 | -50,416,457 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,416,457.
Example:
1 x 50,416,457 = 50,416,457
and
-1 x -50,416,457 = 50,416,457
Notice both answers equal 50,416,457
With that explanation out of the way, let's continue. Next, we take the number 50,416,457 and divide it by 2:
50,416,457 ÷ 2 = 25,208,228.5
If the quotient is a whole number, then 2 and 25,208,228.5 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 | 50,416,457 | |
| -1 | -50,416,457 |
Now, we try dividing 50,416,457 by 3:
50,416,457 ÷ 3 = 16,805,485.6667
If the quotient is a whole number, then 3 and 16,805,485.6667 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 | 50,416,457 | |
| -1 | -50,416,457 |
Let's try dividing by 4:
50,416,457 ÷ 4 = 12,604,114.25
If the quotient is a whole number, then 4 and 12,604,114.25 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 | 50,416,457 | |
| -1 | 50,416,457 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 79 | 91 | 553 | 1,027 | 7,013 | 7,189 | 49,091 | 91,169 | 554,027 | 638,183 | 3,878,189 | 7,202,351 | 50,416,457 |
| -1 | -7 | -13 | -79 | -91 | -553 | -1,027 | -7,013 | -7,189 | -49,091 | -91,169 | -554,027 | -638,183 | -3,878,189 | -7,202,351 | -50,416,457 |
