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 50,519,407, 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 | 50,519,407 | |
| -1 | -50,519,407 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,519,407.
Example:
1 x 50,519,407 = 50,519,407
and
-1 x -50,519,407 = 50,519,407
Notice both answers equal 50,519,407
With that explanation out of the way, let's continue. Next, we take the number 50,519,407 and divide it by 2:
50,519,407 ÷ 2 = 25,259,703.5
If the quotient is a whole number, then 2 and 25,259,703.5 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 | 50,519,407 | |
| -1 | -50,519,407 |
Now, we try dividing 50,519,407 by 3:
50,519,407 ÷ 3 = 16,839,802.3333
If the quotient is a whole number, then 3 and 16,839,802.3333 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 | 50,519,407 | |
| -1 | -50,519,407 |
Let's try dividing by 4:
50,519,407 ÷ 4 = 12,629,851.75
If the quotient is a whole number, then 4 and 12,629,851.75 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 | 50,519,407 | |
| -1 | 50,519,407 |
If you did it right, you will end up with this table:
| 1 | 47 | 61 | 67 | 263 | 2,867 | 3,149 | 4,087 | 12,361 | 16,043 | 17,621 | 192,089 | 754,021 | 828,187 | 1,074,881 | 50,519,407 |
| -1 | -47 | -61 | -67 | -263 | -2,867 | -3,149 | -4,087 | -12,361 | -16,043 | -17,621 | -192,089 | -754,021 | -828,187 | -1,074,881 | -50,519,407 |
