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 51,122,255, 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 | 51,122,255 | |
| -1 | -51,122,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,122,255.
Example:
1 x 51,122,255 = 51,122,255
and
-1 x -51,122,255 = 51,122,255
Notice both answers equal 51,122,255
With that explanation out of the way, let's continue. Next, we take the number 51,122,255 and divide it by 2:
51,122,255 ÷ 2 = 25,561,127.5
If the quotient is a whole number, then 2 and 25,561,127.5 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 | 51,122,255 | |
| -1 | -51,122,255 |
Now, we try dividing 51,122,255 by 3:
51,122,255 ÷ 3 = 17,040,751.6667
If the quotient is a whole number, then 3 and 17,040,751.6667 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 | 51,122,255 | |
| -1 | -51,122,255 |
Let's try dividing by 4:
51,122,255 ÷ 4 = 12,780,563.75
If the quotient is a whole number, then 4 and 12,780,563.75 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 | 51,122,255 | |
| -1 | 51,122,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 31 | 95 | 155 | 589 | 2,945 | 17,359 | 86,795 | 329,821 | 538,129 | 1,649,105 | 2,690,645 | 10,224,451 | 51,122,255 |
| -1 | -5 | -19 | -31 | -95 | -155 | -589 | -2,945 | -17,359 | -86,795 | -329,821 | -538,129 | -1,649,105 | -2,690,645 | -10,224,451 | -51,122,255 |
