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 51,014,375, 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 | 51,014,375 | |
| -1 | -51,014,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,014,375.
Example:
1 x 51,014,375 = 51,014,375
and
-1 x -51,014,375 = 51,014,375
Notice both answers equal 51,014,375
With that explanation out of the way, let's continue. Next, we take the number 51,014,375 and divide it by 2:
51,014,375 ÷ 2 = 25,507,187.5
If the quotient is a whole number, then 2 and 25,507,187.5 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 | 51,014,375 | |
| -1 | -51,014,375 |
Now, we try dividing 51,014,375 by 3:
51,014,375 ÷ 3 = 17,004,791.6667
If the quotient is a whole number, then 3 and 17,004,791.6667 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 | 51,014,375 | |
| -1 | -51,014,375 |
Let's try dividing by 4:
51,014,375 ÷ 4 = 12,753,593.75
If the quotient is a whole number, then 4 and 12,753,593.75 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 | 51,014,375 | |
| -1 | 51,014,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 125 | 155 | 625 | 775 | 2,633 | 3,875 | 13,165 | 19,375 | 65,825 | 81,623 | 329,125 | 408,115 | 1,645,625 | 2,040,575 | 10,202,875 | 51,014,375 |
| -1 | -5 | -25 | -31 | -125 | -155 | -625 | -775 | -2,633 | -3,875 | -13,165 | -19,375 | -65,825 | -81,623 | -329,125 | -408,115 | -1,645,625 | -2,040,575 | -10,202,875 | -51,014,375 |
