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 30,455,711, 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 | 30,455,711 | |
| -1 | -30,455,711 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,455,711.
Example:
1 x 30,455,711 = 30,455,711
and
-1 x -30,455,711 = 30,455,711
Notice both answers equal 30,455,711
With that explanation out of the way, let's continue. Next, we take the number 30,455,711 and divide it by 2:
30,455,711 ÷ 2 = 15,227,855.5
If the quotient is a whole number, then 2 and 15,227,855.5 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 | 30,455,711 | |
| -1 | -30,455,711 |
Now, we try dividing 30,455,711 by 3:
30,455,711 ÷ 3 = 10,151,903.6667
If the quotient is a whole number, then 3 and 10,151,903.6667 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 | 30,455,711 | |
| -1 | -30,455,711 |
Let's try dividing by 4:
30,455,711 ÷ 4 = 7,613,927.75
If the quotient is a whole number, then 4 and 7,613,927.75 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 | 30,455,711 | |
| -1 | 30,455,711 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 89 | 143 | 979 | 1,157 | 2,393 | 12,727 | 26,323 | 31,109 | 212,977 | 342,199 | 2,342,747 | 2,768,701 | 30,455,711 |
| -1 | -11 | -13 | -89 | -143 | -979 | -1,157 | -2,393 | -12,727 | -26,323 | -31,109 | -212,977 | -342,199 | -2,342,747 | -2,768,701 | -30,455,711 |
