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 50,051,515, 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 | 50,051,515 | |
| -1 | -50,051,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,051,515.
Example:
1 x 50,051,515 = 50,051,515
and
-1 x -50,051,515 = 50,051,515
Notice both answers equal 50,051,515
With that explanation out of the way, let's continue. Next, we take the number 50,051,515 and divide it by 2:
50,051,515 ÷ 2 = 25,025,757.5
If the quotient is a whole number, then 2 and 25,025,757.5 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 | 50,051,515 | |
| -1 | -50,051,515 |
Now, we try dividing 50,051,515 by 3:
50,051,515 ÷ 3 = 16,683,838.3333
If the quotient is a whole number, then 3 and 16,683,838.3333 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 | 50,051,515 | |
| -1 | -50,051,515 |
Let's try dividing by 4:
50,051,515 ÷ 4 = 12,512,878.75
If the quotient is a whole number, then 4 and 12,512,878.75 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 | 50,051,515 | |
| -1 | 50,051,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 97 | 155 | 485 | 3,007 | 3,329 | 15,035 | 16,645 | 103,199 | 322,913 | 515,995 | 1,614,565 | 10,010,303 | 50,051,515 |
| -1 | -5 | -31 | -97 | -155 | -485 | -3,007 | -3,329 | -15,035 | -16,645 | -103,199 | -322,913 | -515,995 | -1,614,565 | -10,010,303 | -50,051,515 |
