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 3,021,019, 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 | 3,021,019 | |
| -1 | -3,021,019 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,021,019.
Example:
1 x 3,021,019 = 3,021,019
and
-1 x -3,021,019 = 3,021,019
Notice both answers equal 3,021,019
With that explanation out of the way, let's continue. Next, we take the number 3,021,019 and divide it by 2:
3,021,019 ÷ 2 = 1,510,509.5
If the quotient is a whole number, then 2 and 1,510,509.5 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 | 3,021,019 | |
| -1 | -3,021,019 |
Now, we try dividing 3,021,019 by 3:
3,021,019 ÷ 3 = 1,007,006.3333
If the quotient is a whole number, then 3 and 1,007,006.3333 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 | 3,021,019 | |
| -1 | -3,021,019 |
Let's try dividing by 4:
3,021,019 ÷ 4 = 755,254.75
If the quotient is a whole number, then 4 and 755,254.75 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 | 3,021,019 | |
| -1 | 3,021,019 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 47 | 199 | 323 | 799 | 893 | 3,383 | 3,781 | 9,353 | 15,181 | 64,277 | 159,001 | 177,707 | 3,021,019 |
| -1 | -17 | -19 | -47 | -199 | -323 | -799 | -893 | -3,383 | -3,781 | -9,353 | -15,181 | -64,277 | -159,001 | -177,707 | -3,021,019 |
