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 50,272,313, 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 | 50,272,313 | |
| -1 | -50,272,313 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,272,313.
Example:
1 x 50,272,313 = 50,272,313
and
-1 x -50,272,313 = 50,272,313
Notice both answers equal 50,272,313
With that explanation out of the way, let's continue. Next, we take the number 50,272,313 and divide it by 2:
50,272,313 ÷ 2 = 25,136,156.5
If the quotient is a whole number, then 2 and 25,136,156.5 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 | 50,272,313 | |
| -1 | -50,272,313 |
Now, we try dividing 50,272,313 by 3:
50,272,313 ÷ 3 = 16,757,437.6667
If the quotient is a whole number, then 3 and 16,757,437.6667 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 | 50,272,313 | |
| -1 | -50,272,313 |
Let's try dividing by 4:
50,272,313 ÷ 4 = 12,568,078.25
If the quotient is a whole number, then 4 and 12,568,078.25 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 | 50,272,313 | |
| -1 | 50,272,313 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 233 | 1,631 | 2,371 | 3,029 | 16,597 | 21,203 | 30,823 | 215,761 | 552,443 | 3,867,101 | 7,181,759 | 50,272,313 |
| -1 | -7 | -13 | -91 | -233 | -1,631 | -2,371 | -3,029 | -16,597 | -21,203 | -30,823 | -215,761 | -552,443 | -3,867,101 | -7,181,759 | -50,272,313 |
