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 51,414,715, 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 | 51,414,715 | |
| -1 | -51,414,715 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,414,715.
Example:
1 x 51,414,715 = 51,414,715
and
-1 x -51,414,715 = 51,414,715
Notice both answers equal 51,414,715
With that explanation out of the way, let's continue. Next, we take the number 51,414,715 and divide it by 2:
51,414,715 ÷ 2 = 25,707,357.5
If the quotient is a whole number, then 2 and 25,707,357.5 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 | 51,414,715 | |
| -1 | -51,414,715 |
Now, we try dividing 51,414,715 by 3:
51,414,715 ÷ 3 = 17,138,238.3333
If the quotient is a whole number, then 3 and 17,138,238.3333 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 | 51,414,715 | |
| -1 | -51,414,715 |
Let's try dividing by 4:
51,414,715 ÷ 4 = 12,853,678.75
If the quotient is a whole number, then 4 and 12,853,678.75 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 | 51,414,715 | |
| -1 | 51,414,715 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 121 | 187 | 605 | 935 | 2,057 | 4,999 | 10,285 | 24,995 | 54,989 | 84,983 | 274,945 | 424,915 | 604,879 | 934,813 | 3,024,395 | 4,674,065 | 10,282,943 | 51,414,715 |
| -1 | -5 | -11 | -17 | -55 | -85 | -121 | -187 | -605 | -935 | -2,057 | -4,999 | -10,285 | -24,995 | -54,989 | -84,983 | -274,945 | -424,915 | -604,879 | -934,813 | -3,024,395 | -4,674,065 | -10,282,943 | -51,414,715 |
