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 50,120,323, 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 | 50,120,323 | |
| -1 | -50,120,323 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,120,323.
Example:
1 x 50,120,323 = 50,120,323
and
-1 x -50,120,323 = 50,120,323
Notice both answers equal 50,120,323
With that explanation out of the way, let's continue. Next, we take the number 50,120,323 and divide it by 2:
50,120,323 ÷ 2 = 25,060,161.5
If the quotient is a whole number, then 2 and 25,060,161.5 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 | 50,120,323 | |
| -1 | -50,120,323 |
Now, we try dividing 50,120,323 by 3:
50,120,323 ÷ 3 = 16,706,774.3333
If the quotient is a whole number, then 3 and 16,706,774.3333 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 | 50,120,323 | |
| -1 | -50,120,323 |
Let's try dividing by 4:
50,120,323 ÷ 4 = 12,530,080.75
If the quotient is a whole number, then 4 and 12,530,080.75 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 | 50,120,323 | |
| -1 | 50,120,323 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 59 | 319 | 649 | 1,711 | 2,663 | 18,821 | 29,293 | 77,227 | 157,117 | 849,497 | 1,728,287 | 4,556,393 | 50,120,323 |
| -1 | -11 | -29 | -59 | -319 | -649 | -1,711 | -2,663 | -18,821 | -29,293 | -77,227 | -157,117 | -849,497 | -1,728,287 | -4,556,393 | -50,120,323 |
