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 50,380,253, 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 | 50,380,253 | |
| -1 | -50,380,253 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,380,253.
Example:
1 x 50,380,253 = 50,380,253
and
-1 x -50,380,253 = 50,380,253
Notice both answers equal 50,380,253
With that explanation out of the way, let's continue. Next, we take the number 50,380,253 and divide it by 2:
50,380,253 ÷ 2 = 25,190,126.5
If the quotient is a whole number, then 2 and 25,190,126.5 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 | 50,380,253 | |
| -1 | -50,380,253 |
Now, we try dividing 50,380,253 by 3:
50,380,253 ÷ 3 = 16,793,417.6667
If the quotient is a whole number, then 3 and 16,793,417.6667 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 | 50,380,253 | |
| -1 | -50,380,253 |
Let's try dividing by 4:
50,380,253 ÷ 4 = 12,595,063.25
If the quotient is a whole number, then 4 and 12,595,063.25 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 | 50,380,253 | |
| -1 | 50,380,253 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 83 | 581 | 913 | 6,391 | 7,883 | 55,181 | 86,713 | 606,991 | 654,289 | 4,580,023 | 7,197,179 | 50,380,253 |
| -1 | -7 | -11 | -77 | -83 | -581 | -913 | -6,391 | -7,883 | -55,181 | -86,713 | -606,991 | -654,289 | -4,580,023 | -7,197,179 | -50,380,253 |
