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 30,512,029, 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 | 30,512,029 | |
| -1 | -30,512,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,512,029.
Example:
1 x 30,512,029 = 30,512,029
and
-1 x -30,512,029 = 30,512,029
Notice both answers equal 30,512,029
With that explanation out of the way, let's continue. Next, we take the number 30,512,029 and divide it by 2:
30,512,029 ÷ 2 = 15,256,014.5
If the quotient is a whole number, then 2 and 15,256,014.5 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 | 30,512,029 | |
| -1 | -30,512,029 |
Now, we try dividing 30,512,029 by 3:
30,512,029 ÷ 3 = 10,170,676.3333
If the quotient is a whole number, then 3 and 10,170,676.3333 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 | 30,512,029 | |
| -1 | -30,512,029 |
Let's try dividing by 4:
30,512,029 ÷ 4 = 7,628,007.25
If the quotient is a whole number, then 4 and 7,628,007.25 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 | 30,512,029 | |
| -1 | 30,512,029 |
If you did it right, you will end up with this table:
| 1 | 31 | 73 | 97 | 139 | 2,263 | 3,007 | 4,309 | 7,081 | 10,147 | 13,483 | 219,511 | 314,557 | 417,973 | 984,259 | 30,512,029 |
| -1 | -31 | -73 | -97 | -139 | -2,263 | -3,007 | -4,309 | -7,081 | -10,147 | -13,483 | -219,511 | -314,557 | -417,973 | -984,259 | -30,512,029 |
