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 30,382,807, 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 | 30,382,807 | |
| -1 | -30,382,807 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,382,807.
Example:
1 x 30,382,807 = 30,382,807
and
-1 x -30,382,807 = 30,382,807
Notice both answers equal 30,382,807
With that explanation out of the way, let's continue. Next, we take the number 30,382,807 and divide it by 2:
30,382,807 ÷ 2 = 15,191,403.5
If the quotient is a whole number, then 2 and 15,191,403.5 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 | 30,382,807 | |
| -1 | -30,382,807 |
Now, we try dividing 30,382,807 by 3:
30,382,807 ÷ 3 = 10,127,602.3333
If the quotient is a whole number, then 3 and 10,127,602.3333 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 | 30,382,807 | |
| -1 | -30,382,807 |
Let's try dividing by 4:
30,382,807 ÷ 4 = 7,595,701.75
If the quotient is a whole number, then 4 and 7,595,701.75 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 | 30,382,807 | |
| -1 | 30,382,807 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 29 | 91 | 203 | 377 | 397 | 841 | 2,639 | 2,779 | 5,161 | 5,887 | 10,933 | 11,513 | 36,127 | 76,531 | 80,591 | 149,669 | 333,877 | 1,047,683 | 2,337,139 | 4,340,401 | 30,382,807 |
| -1 | -7 | -13 | -29 | -91 | -203 | -377 | -397 | -841 | -2,639 | -2,779 | -5,161 | -5,887 | -10,933 | -11,513 | -36,127 | -76,531 | -80,591 | -149,669 | -333,877 | -1,047,683 | -2,337,139 | -4,340,401 | -30,382,807 |
