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 30,474,941, 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 | 30,474,941 | |
| -1 | -30,474,941 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,474,941.
Example:
1 x 30,474,941 = 30,474,941
and
-1 x -30,474,941 = 30,474,941
Notice both answers equal 30,474,941
With that explanation out of the way, let's continue. Next, we take the number 30,474,941 and divide it by 2:
30,474,941 ÷ 2 = 15,237,470.5
If the quotient is a whole number, then 2 and 15,237,470.5 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 | 30,474,941 | |
| -1 | -30,474,941 |
Now, we try dividing 30,474,941 by 3:
30,474,941 ÷ 3 = 10,158,313.6667
If the quotient is a whole number, then 3 and 10,158,313.6667 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 | 30,474,941 | |
| -1 | -30,474,941 |
Let's try dividing by 4:
30,474,941 ÷ 4 = 7,618,735.25
If the quotient is a whole number, then 4 and 7,618,735.25 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 | 30,474,941 | |
| -1 | 30,474,941 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 211 | 329 | 439 | 1,477 | 3,073 | 9,917 | 20,633 | 69,419 | 92,629 | 144,431 | 648,403 | 4,353,563 | 30,474,941 |
| -1 | -7 | -47 | -211 | -329 | -439 | -1,477 | -3,073 | -9,917 | -20,633 | -69,419 | -92,629 | -144,431 | -648,403 | -4,353,563 | -30,474,941 |
