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 50,245,027, 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 | 50,245,027 | |
| -1 | -50,245,027 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,245,027.
Example:
1 x 50,245,027 = 50,245,027
and
-1 x -50,245,027 = 50,245,027
Notice both answers equal 50,245,027
With that explanation out of the way, let's continue. Next, we take the number 50,245,027 and divide it by 2:
50,245,027 ÷ 2 = 25,122,513.5
If the quotient is a whole number, then 2 and 25,122,513.5 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 | 50,245,027 | |
| -1 | -50,245,027 |
Now, we try dividing 50,245,027 by 3:
50,245,027 ÷ 3 = 16,748,342.3333
If the quotient is a whole number, then 3 and 16,748,342.3333 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 | 50,245,027 | |
| -1 | -50,245,027 |
Let's try dividing by 4:
50,245,027 ÷ 4 = 12,561,256.75
If the quotient is a whole number, then 4 and 12,561,256.75 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 | 50,245,027 | |
| -1 | 50,245,027 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 79 | 301 | 553 | 2,113 | 3,397 | 14,791 | 23,779 | 90,859 | 166,927 | 636,013 | 1,168,489 | 7,177,861 | 50,245,027 |
| -1 | -7 | -43 | -79 | -301 | -553 | -2,113 | -3,397 | -14,791 | -23,779 | -90,859 | -166,927 | -636,013 | -1,168,489 | -7,177,861 | -50,245,027 |
