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 30,534,427, 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 | 30,534,427 | |
| -1 | -30,534,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,534,427.
Example:
1 x 30,534,427 = 30,534,427
and
-1 x -30,534,427 = 30,534,427
Notice both answers equal 30,534,427
With that explanation out of the way, let's continue. Next, we take the number 30,534,427 and divide it by 2:
30,534,427 ÷ 2 = 15,267,213.5
If the quotient is a whole number, then 2 and 15,267,213.5 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 | 30,534,427 | |
| -1 | -30,534,427 |
Now, we try dividing 30,534,427 by 3:
30,534,427 ÷ 3 = 10,178,142.3333
If the quotient is a whole number, then 3 and 10,178,142.3333 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 | 30,534,427 | |
| -1 | -30,534,427 |
Let's try dividing by 4:
30,534,427 ÷ 4 = 7,633,606.75
If the quotient is a whole number, then 4 and 7,633,606.75 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 | 30,534,427 | |
| -1 | 30,534,427 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 257 | 1,543 | 1,799 | 2,827 | 10,801 | 16,973 | 19,789 | 118,811 | 396,551 | 2,775,857 | 4,362,061 | 30,534,427 |
| -1 | -7 | -11 | -77 | -257 | -1,543 | -1,799 | -2,827 | -10,801 | -16,973 | -19,789 | -118,811 | -396,551 | -2,775,857 | -4,362,061 | -30,534,427 |
