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 51,302,405, 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 | 51,302,405 | |
| -1 | -51,302,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,302,405.
Example:
1 x 51,302,405 = 51,302,405
and
-1 x -51,302,405 = 51,302,405
Notice both answers equal 51,302,405
With that explanation out of the way, let's continue. Next, we take the number 51,302,405 and divide it by 2:
51,302,405 ÷ 2 = 25,651,202.5
If the quotient is a whole number, then 2 and 25,651,202.5 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 | 51,302,405 | |
| -1 | -51,302,405 |
Now, we try dividing 51,302,405 by 3:
51,302,405 ÷ 3 = 17,100,801.6667
If the quotient is a whole number, then 3 and 17,100,801.6667 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 | 51,302,405 | |
| -1 | -51,302,405 |
Let's try dividing by 4:
51,302,405 ÷ 4 = 12,825,601.25
If the quotient is a whole number, then 4 and 12,825,601.25 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 | 51,302,405 | |
| -1 | 51,302,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 133,253 | 666,265 | 932,771 | 1,465,783 | 4,663,855 | 7,328,915 | 10,260,481 | 51,302,405 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -133,253 | -666,265 | -932,771 | -1,465,783 | -4,663,855 | -7,328,915 | -10,260,481 | -51,302,405 |
