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 50,661,455, 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 | 50,661,455 | |
| -1 | -50,661,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,661,455.
Example:
1 x 50,661,455 = 50,661,455
and
-1 x -50,661,455 = 50,661,455
Notice both answers equal 50,661,455
With that explanation out of the way, let's continue. Next, we take the number 50,661,455 and divide it by 2:
50,661,455 ÷ 2 = 25,330,727.5
If the quotient is a whole number, then 2 and 25,330,727.5 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 | 50,661,455 | |
| -1 | -50,661,455 |
Now, we try dividing 50,661,455 by 3:
50,661,455 ÷ 3 = 16,887,151.6667
If the quotient is a whole number, then 3 and 16,887,151.6667 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 | 50,661,455 | |
| -1 | -50,661,455 |
Let's try dividing by 4:
50,661,455 ÷ 4 = 12,665,363.75
If the quotient is a whole number, then 4 and 12,665,363.75 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 | 50,661,455 | |
| -1 | 50,661,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 743 | 1,049 | 3,715 | 5,245 | 9,659 | 13,637 | 48,295 | 68,185 | 779,407 | 3,897,035 | 10,132,291 | 50,661,455 |
| -1 | -5 | -13 | -65 | -743 | -1,049 | -3,715 | -5,245 | -9,659 | -13,637 | -48,295 | -68,185 | -779,407 | -3,897,035 | -10,132,291 | -50,661,455 |
