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 50,550,499, 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 | 50,550,499 | |
| -1 | -50,550,499 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,550,499.
Example:
1 x 50,550,499 = 50,550,499
and
-1 x -50,550,499 = 50,550,499
Notice both answers equal 50,550,499
With that explanation out of the way, let's continue. Next, we take the number 50,550,499 and divide it by 2:
50,550,499 ÷ 2 = 25,275,249.5
If the quotient is a whole number, then 2 and 25,275,249.5 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 | 50,550,499 | |
| -1 | -50,550,499 |
Now, we try dividing 50,550,499 by 3:
50,550,499 ÷ 3 = 16,850,166.3333
If the quotient is a whole number, then 3 and 16,850,166.3333 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 | 50,550,499 | |
| -1 | -50,550,499 |
Let's try dividing by 4:
50,550,499 ÷ 4 = 12,637,624.75
If the quotient is a whole number, then 4 and 12,637,624.75 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 | 50,550,499 | |
| -1 | 50,550,499 |
If you did it right, you will end up with this table:
| 1 | 41 | 43 | 53 | 541 | 1,763 | 2,173 | 2,279 | 22,181 | 23,263 | 28,673 | 93,439 | 953,783 | 1,175,593 | 1,232,939 | 50,550,499 |
| -1 | -41 | -43 | -53 | -541 | -1,763 | -2,173 | -2,279 | -22,181 | -23,263 | -28,673 | -93,439 | -953,783 | -1,175,593 | -1,232,939 | -50,550,499 |
