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 30,606,325, 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 | 30,606,325 | |
| -1 | -30,606,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,606,325.
Example:
1 x 30,606,325 = 30,606,325
and
-1 x -30,606,325 = 30,606,325
Notice both answers equal 30,606,325
With that explanation out of the way, let's continue. Next, we take the number 30,606,325 and divide it by 2:
30,606,325 ÷ 2 = 15,303,162.5
If the quotient is a whole number, then 2 and 15,303,162.5 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 | 30,606,325 | |
| -1 | -30,606,325 |
Now, we try dividing 30,606,325 by 3:
30,606,325 ÷ 3 = 10,202,108.3333
If the quotient is a whole number, then 3 and 10,202,108.3333 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 | 30,606,325 | |
| -1 | -30,606,325 |
Let's try dividing by 4:
30,606,325 ÷ 4 = 7,651,581.25
If the quotient is a whole number, then 4 and 7,651,581.25 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 | 30,606,325 | |
| -1 | 30,606,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 43 | 71 | 215 | 355 | 401 | 1,075 | 1,775 | 2,005 | 3,053 | 10,025 | 15,265 | 17,243 | 28,471 | 76,325 | 86,215 | 142,355 | 431,075 | 711,775 | 1,224,253 | 6,121,265 | 30,606,325 |
| -1 | -5 | -25 | -43 | -71 | -215 | -355 | -401 | -1,075 | -1,775 | -2,005 | -3,053 | -10,025 | -15,265 | -17,243 | -28,471 | -76,325 | -86,215 | -142,355 | -431,075 | -711,775 | -1,224,253 | -6,121,265 | -30,606,325 |
