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 3,111,119, 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 | 3,111,119 | |
| -1 | -3,111,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,111,119.
Example:
1 x 3,111,119 = 3,111,119
and
-1 x -3,111,119 = 3,111,119
Notice both answers equal 3,111,119
With that explanation out of the way, let's continue. Next, we take the number 3,111,119 and divide it by 2:
3,111,119 ÷ 2 = 1,555,559.5
If the quotient is a whole number, then 2 and 1,555,559.5 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 | 3,111,119 | |
| -1 | -3,111,119 |
Now, we try dividing 3,111,119 by 3:
3,111,119 ÷ 3 = 1,037,039.6667
If the quotient is a whole number, then 3 and 1,037,039.6667 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 | 3,111,119 | |
| -1 | -3,111,119 |
Let's try dividing by 4:
3,111,119 ÷ 4 = 777,779.75
If the quotient is a whole number, then 4 and 777,779.75 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 | 3,111,119 | |
| -1 | 3,111,119 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 127 | 131 | 187 | 1,397 | 1,441 | 2,159 | 2,227 | 16,637 | 23,749 | 24,497 | 183,007 | 282,829 | 3,111,119 |
| -1 | -11 | -17 | -127 | -131 | -187 | -1,397 | -1,441 | -2,159 | -2,227 | -16,637 | -23,749 | -24,497 | -183,007 | -282,829 | -3,111,119 |
