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 30,082,507, 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 | 30,082,507 | |
| -1 | -30,082,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,082,507.
Example:
1 x 30,082,507 = 30,082,507
and
-1 x -30,082,507 = 30,082,507
Notice both answers equal 30,082,507
With that explanation out of the way, let's continue. Next, we take the number 30,082,507 and divide it by 2:
30,082,507 ÷ 2 = 15,041,253.5
If the quotient is a whole number, then 2 and 15,041,253.5 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 | 30,082,507 | |
| -1 | -30,082,507 |
Now, we try dividing 30,082,507 by 3:
30,082,507 ÷ 3 = 10,027,502.3333
If the quotient is a whole number, then 3 and 10,027,502.3333 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 | 30,082,507 | |
| -1 | -30,082,507 |
Let's try dividing by 4:
30,082,507 ÷ 4 = 7,520,626.75
If the quotient is a whole number, then 4 and 7,520,626.75 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 | 30,082,507 | |
| -1 | 30,082,507 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 59 | 91 | 169 | 413 | 431 | 767 | 1,183 | 3,017 | 5,369 | 5,603 | 9,971 | 25,429 | 39,221 | 69,797 | 72,839 | 178,003 | 330,577 | 509,873 | 2,314,039 | 4,297,501 | 30,082,507 |
| -1 | -7 | -13 | -59 | -91 | -169 | -413 | -431 | -767 | -1,183 | -3,017 | -5,369 | -5,603 | -9,971 | -25,429 | -39,221 | -69,797 | -72,839 | -178,003 | -330,577 | -509,873 | -2,314,039 | -4,297,501 | -30,082,507 |
