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 3,025,009, 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 | 3,025,009 | |
| -1 | -3,025,009 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,025,009.
Example:
1 x 3,025,009 = 3,025,009
and
-1 x -3,025,009 = 3,025,009
Notice both answers equal 3,025,009
With that explanation out of the way, let's continue. Next, we take the number 3,025,009 and divide it by 2:
3,025,009 ÷ 2 = 1,512,504.5
If the quotient is a whole number, then 2 and 1,512,504.5 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 | 3,025,009 | |
| -1 | -3,025,009 |
Now, we try dividing 3,025,009 by 3:
3,025,009 ÷ 3 = 1,008,336.3333
If the quotient is a whole number, then 3 and 1,008,336.3333 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 | 3,025,009 | |
| -1 | -3,025,009 |
Let's try dividing by 4:
3,025,009 ÷ 4 = 756,252.25
If the quotient is a whole number, then 4 and 756,252.25 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 | 3,025,009 | |
| -1 | 3,025,009 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 37 | 247 | 331 | 481 | 703 | 4,303 | 6,289 | 9,139 | 12,247 | 81,757 | 159,211 | 232,693 | 3,025,009 |
| -1 | -13 | -19 | -37 | -247 | -331 | -481 | -703 | -4,303 | -6,289 | -9,139 | -12,247 | -81,757 | -159,211 | -232,693 | -3,025,009 |
