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 3,009,425, 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 | 3,009,425 | |
| -1 | -3,009,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,009,425.
Example:
1 x 3,009,425 = 3,009,425
and
-1 x -3,009,425 = 3,009,425
Notice both answers equal 3,009,425
With that explanation out of the way, let's continue. Next, we take the number 3,009,425 and divide it by 2:
3,009,425 ÷ 2 = 1,504,712.5
If the quotient is a whole number, then 2 and 1,504,712.5 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 | 3,009,425 | |
| -1 | -3,009,425 |
Now, we try dividing 3,009,425 by 3:
3,009,425 ÷ 3 = 1,003,141.6667
If the quotient is a whole number, then 3 and 1,003,141.6667 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 | 3,009,425 | |
| -1 | -3,009,425 |
Let's try dividing by 4:
3,009,425 ÷ 4 = 752,356.25
If the quotient is a whole number, then 4 and 752,356.25 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 | 3,009,425 | |
| -1 | 3,009,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 73 | 85 | 97 | 365 | 425 | 485 | 1,241 | 1,649 | 1,825 | 2,425 | 6,205 | 7,081 | 8,245 | 31,025 | 35,405 | 41,225 | 120,377 | 177,025 | 601,885 | 3,009,425 |
| -1 | -5 | -17 | -25 | -73 | -85 | -97 | -365 | -425 | -485 | -1,241 | -1,649 | -1,825 | -2,425 | -6,205 | -7,081 | -8,245 | -31,025 | -35,405 | -41,225 | -120,377 | -177,025 | -601,885 | -3,009,425 |
