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 3,112,351, 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 | 3,112,351 | |
| -1 | -3,112,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,112,351.
Example:
1 x 3,112,351 = 3,112,351
and
-1 x -3,112,351 = 3,112,351
Notice both answers equal 3,112,351
With that explanation out of the way, let's continue. Next, we take the number 3,112,351 and divide it by 2:
3,112,351 ÷ 2 = 1,556,175.5
If the quotient is a whole number, then 2 and 1,556,175.5 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 | 3,112,351 | |
| -1 | -3,112,351 |
Now, we try dividing 3,112,351 by 3:
3,112,351 ÷ 3 = 1,037,450.3333
If the quotient is a whole number, then 3 and 1,037,450.3333 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 | 3,112,351 | |
| -1 | -3,112,351 |
Let's try dividing by 4:
3,112,351 ÷ 4 = 778,087.75
If the quotient is a whole number, then 4 and 778,087.75 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 | 3,112,351 | |
| -1 | 3,112,351 |
If you did it right, you will end up with this table:
| 1 | 11 | 41 | 67 | 103 | 451 | 737 | 1,133 | 2,747 | 4,223 | 6,901 | 30,217 | 46,453 | 75,911 | 282,941 | 3,112,351 |
| -1 | -11 | -41 | -67 | -103 | -451 | -737 | -1,133 | -2,747 | -4,223 | -6,901 | -30,217 | -46,453 | -75,911 | -282,941 | -3,112,351 |
