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 3,330,775, 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 | 3,330,775 | |
| -1 | -3,330,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,330,775.
Example:
1 x 3,330,775 = 3,330,775
and
-1 x -3,330,775 = 3,330,775
Notice both answers equal 3,330,775
With that explanation out of the way, let's continue. Next, we take the number 3,330,775 and divide it by 2:
3,330,775 ÷ 2 = 1,665,387.5
If the quotient is a whole number, then 2 and 1,665,387.5 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 | 3,330,775 | |
| -1 | -3,330,775 |
Now, we try dividing 3,330,775 by 3:
3,330,775 ÷ 3 = 1,110,258.3333
If the quotient is a whole number, then 3 and 1,110,258.3333 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 | 3,330,775 | |
| -1 | -3,330,775 |
Let's try dividing by 4:
3,330,775 ÷ 4 = 832,693.75
If the quotient is a whole number, then 4 and 832,693.75 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 | 3,330,775 | |
| -1 | 3,330,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 49 | 175 | 245 | 1,225 | 2,719 | 13,595 | 19,033 | 67,975 | 95,165 | 133,231 | 475,825 | 666,155 | 3,330,775 |
| -1 | -5 | -7 | -25 | -35 | -49 | -175 | -245 | -1,225 | -2,719 | -13,595 | -19,033 | -67,975 | -95,165 | -133,231 | -475,825 | -666,155 | -3,330,775 |
