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 30,341,047, 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 | 30,341,047 | |
| -1 | -30,341,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,341,047.
Example:
1 x 30,341,047 = 30,341,047
and
-1 x -30,341,047 = 30,341,047
Notice both answers equal 30,341,047
With that explanation out of the way, let's continue. Next, we take the number 30,341,047 and divide it by 2:
30,341,047 ÷ 2 = 15,170,523.5
If the quotient is a whole number, then 2 and 15,170,523.5 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 | 30,341,047 | |
| -1 | -30,341,047 |
Now, we try dividing 30,341,047 by 3:
30,341,047 ÷ 3 = 10,113,682.3333
If the quotient is a whole number, then 3 and 10,113,682.3333 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 | 30,341,047 | |
| -1 | -30,341,047 |
Let's try dividing by 4:
30,341,047 ÷ 4 = 7,585,261.75
If the quotient is a whole number, then 4 and 7,585,261.75 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 | 30,341,047 | |
| -1 | 30,341,047 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 227 | 319 | 419 | 2,497 | 4,609 | 6,583 | 12,151 | 72,413 | 95,113 | 133,661 | 1,046,243 | 2,758,277 | 30,341,047 |
| -1 | -11 | -29 | -227 | -319 | -419 | -2,497 | -4,609 | -6,583 | -12,151 | -72,413 | -95,113 | -133,661 | -1,046,243 | -2,758,277 | -30,341,047 |
