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 3,112,445, 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 | 3,112,445 | |
| -1 | -3,112,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,112,445.
Example:
1 x 3,112,445 = 3,112,445
and
-1 x -3,112,445 = 3,112,445
Notice both answers equal 3,112,445
With that explanation out of the way, let's continue. Next, we take the number 3,112,445 and divide it by 2:
3,112,445 ÷ 2 = 1,556,222.5
If the quotient is a whole number, then 2 and 1,556,222.5 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 | 3,112,445 | |
| -1 | -3,112,445 |
Now, we try dividing 3,112,445 by 3:
3,112,445 ÷ 3 = 1,037,481.6667
If the quotient is a whole number, then 3 and 1,037,481.6667 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 | 3,112,445 | |
| -1 | -3,112,445 |
Let's try dividing by 4:
3,112,445 ÷ 4 = 778,111.25
If the quotient is a whole number, then 4 and 778,111.25 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 | 3,112,445 | |
| -1 | 3,112,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 5,231 | 26,155 | 36,617 | 88,927 | 183,085 | 444,635 | 622,489 | 3,112,445 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -5,231 | -26,155 | -36,617 | -88,927 | -183,085 | -444,635 | -622,489 | -3,112,445 |
