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 3,007,165, 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 | 3,007,165 | |
| -1 | -3,007,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,007,165.
Example:
1 x 3,007,165 = 3,007,165
and
-1 x -3,007,165 = 3,007,165
Notice both answers equal 3,007,165
With that explanation out of the way, let's continue. Next, we take the number 3,007,165 and divide it by 2:
3,007,165 ÷ 2 = 1,503,582.5
If the quotient is a whole number, then 2 and 1,503,582.5 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 | 3,007,165 | |
| -1 | -3,007,165 |
Now, we try dividing 3,007,165 by 3:
3,007,165 ÷ 3 = 1,002,388.3333
If the quotient is a whole number, then 3 and 1,002,388.3333 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 | 3,007,165 | |
| -1 | -3,007,165 |
Let's try dividing by 4:
3,007,165 ÷ 4 = 751,791.25
If the quotient is a whole number, then 4 and 751,791.25 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 | 3,007,165 | |
| -1 | 3,007,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 151 | 569 | 755 | 1,057 | 2,845 | 3,983 | 5,285 | 19,915 | 85,919 | 429,595 | 601,433 | 3,007,165 |
| -1 | -5 | -7 | -35 | -151 | -569 | -755 | -1,057 | -2,845 | -3,983 | -5,285 | -19,915 | -85,919 | -429,595 | -601,433 | -3,007,165 |
