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 50,002,105, 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 | 50,002,105 | |
| -1 | -50,002,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,002,105.
Example:
1 x 50,002,105 = 50,002,105
and
-1 x -50,002,105 = 50,002,105
Notice both answers equal 50,002,105
With that explanation out of the way, let's continue. Next, we take the number 50,002,105 and divide it by 2:
50,002,105 ÷ 2 = 25,001,052.5
If the quotient is a whole number, then 2 and 25,001,052.5 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 | 50,002,105 | |
| -1 | -50,002,105 |
Now, we try dividing 50,002,105 by 3:
50,002,105 ÷ 3 = 16,667,368.3333
If the quotient is a whole number, then 3 and 16,667,368.3333 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 | 50,002,105 | |
| -1 | -50,002,105 |
Let's try dividing by 4:
50,002,105 ÷ 4 = 12,500,526.25
If the quotient is a whole number, then 4 and 12,500,526.25 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 | 50,002,105 | |
| -1 | 50,002,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 83 | 355 | 415 | 1,697 | 5,893 | 8,485 | 29,465 | 120,487 | 140,851 | 602,435 | 704,255 | 10,000,421 | 50,002,105 |
| -1 | -5 | -71 | -83 | -355 | -415 | -1,697 | -5,893 | -8,485 | -29,465 | -120,487 | -140,851 | -602,435 | -704,255 | -10,000,421 | -50,002,105 |
