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 3,034,031, 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 | 3,034,031 | |
| -1 | -3,034,031 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,034,031.
Example:
1 x 3,034,031 = 3,034,031
and
-1 x -3,034,031 = 3,034,031
Notice both answers equal 3,034,031
With that explanation out of the way, let's continue. Next, we take the number 3,034,031 and divide it by 2:
3,034,031 ÷ 2 = 1,517,015.5
If the quotient is a whole number, then 2 and 1,517,015.5 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 | 3,034,031 | |
| -1 | -3,034,031 |
Now, we try dividing 3,034,031 by 3:
3,034,031 ÷ 3 = 1,011,343.6667
If the quotient is a whole number, then 3 and 1,011,343.6667 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 | 3,034,031 | |
| -1 | -3,034,031 |
Let's try dividing by 4:
3,034,031 ÷ 4 = 758,507.75
If the quotient is a whole number, then 4 and 758,507.75 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 | 3,034,031 | |
| -1 | 3,034,031 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 13 | 49 | 77 | 91 | 143 | 433 | 539 | 637 | 1,001 | 3,031 | 4,763 | 5,629 | 7,007 | 21,217 | 33,341 | 39,403 | 61,919 | 233,387 | 275,821 | 433,433 | 3,034,031 |
| -1 | -7 | -11 | -13 | -49 | -77 | -91 | -143 | -433 | -539 | -637 | -1,001 | -3,031 | -4,763 | -5,629 | -7,007 | -21,217 | -33,341 | -39,403 | -61,919 | -233,387 | -275,821 | -433,433 | -3,034,031 |
