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 3,030,775, 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 | 3,030,775 | |
| -1 | -3,030,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,030,775.
Example:
1 x 3,030,775 = 3,030,775
and
-1 x -3,030,775 = 3,030,775
Notice both answers equal 3,030,775
With that explanation out of the way, let's continue. Next, we take the number 3,030,775 and divide it by 2:
3,030,775 ÷ 2 = 1,515,387.5
If the quotient is a whole number, then 2 and 1,515,387.5 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 | 3,030,775 | |
| -1 | -3,030,775 |
Now, we try dividing 3,030,775 by 3:
3,030,775 ÷ 3 = 1,010,258.3333
If the quotient is a whole number, then 3 and 1,010,258.3333 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 | 3,030,775 | |
| -1 | -3,030,775 |
Let's try dividing by 4:
3,030,775 ÷ 4 = 757,693.75
If the quotient is a whole number, then 4 and 757,693.75 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 | 3,030,775 | |
| -1 | 3,030,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 103 | 107 | 275 | 515 | 535 | 1,133 | 1,177 | 2,575 | 2,675 | 5,665 | 5,885 | 11,021 | 28,325 | 29,425 | 55,105 | 121,231 | 275,525 | 606,155 | 3,030,775 |
| -1 | -5 | -11 | -25 | -55 | -103 | -107 | -275 | -515 | -535 | -1,133 | -1,177 | -2,575 | -2,675 | -5,665 | -5,885 | -11,021 | -28,325 | -29,425 | -55,105 | -121,231 | -275,525 | -606,155 | -3,030,775 |
