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 51,030,455, 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 | 51,030,455 | |
| -1 | -51,030,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 51,030,455.
Example:
1 x 51,030,455 = 51,030,455
and
-1 x -51,030,455 = 51,030,455
Notice both answers equal 51,030,455
With that explanation out of the way, let's continue. Next, we take the number 51,030,455 and divide it by 2:
51,030,455 ÷ 2 = 25,515,227.5
If the quotient is a whole number, then 2 and 25,515,227.5 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 | 51,030,455 | |
| -1 | -51,030,455 |
Now, we try dividing 51,030,455 by 3:
51,030,455 ÷ 3 = 17,010,151.6667
If the quotient is a whole number, then 3 and 17,010,151.6667 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 | 51,030,455 | |
| -1 | -51,030,455 |
Let's try dividing by 4:
51,030,455 ÷ 4 = 12,757,613.75
If the quotient is a whole number, then 4 and 12,757,613.75 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 | 51,030,455 | |
| -1 | 51,030,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 379 | 1,895 | 2,653 | 3,847 | 13,265 | 19,235 | 26,929 | 134,645 | 1,458,013 | 7,290,065 | 10,206,091 | 51,030,455 |
| -1 | -5 | -7 | -35 | -379 | -1,895 | -2,653 | -3,847 | -13,265 | -19,235 | -26,929 | -134,645 | -1,458,013 | -7,290,065 | -10,206,091 | -51,030,455 |
