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 50,500,165, 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 | 50,500,165 | |
| -1 | -50,500,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,500,165.
Example:
1 x 50,500,165 = 50,500,165
and
-1 x -50,500,165 = 50,500,165
Notice both answers equal 50,500,165
With that explanation out of the way, let's continue. Next, we take the number 50,500,165 and divide it by 2:
50,500,165 ÷ 2 = 25,250,082.5
If the quotient is a whole number, then 2 and 25,250,082.5 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 | 50,500,165 | |
| -1 | -50,500,165 |
Now, we try dividing 50,500,165 by 3:
50,500,165 ÷ 3 = 16,833,388.3333
If the quotient is a whole number, then 3 and 16,833,388.3333 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 | 50,500,165 | |
| -1 | -50,500,165 |
Let's try dividing by 4:
50,500,165 ÷ 4 = 12,625,041.25
If the quotient is a whole number, then 4 and 12,625,041.25 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 | 50,500,165 | |
| -1 | 50,500,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 59 | 145 | 295 | 1,711 | 5,903 | 8,555 | 29,515 | 171,187 | 348,277 | 855,935 | 1,741,385 | 10,100,033 | 50,500,165 |
| -1 | -5 | -29 | -59 | -145 | -295 | -1,711 | -5,903 | -8,555 | -29,515 | -171,187 | -348,277 | -855,935 | -1,741,385 | -10,100,033 | -50,500,165 |
