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 3,311,365, 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 | 3,311,365 | |
| -1 | -3,311,365 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,311,365.
Example:
1 x 3,311,365 = 3,311,365
and
-1 x -3,311,365 = 3,311,365
Notice both answers equal 3,311,365
With that explanation out of the way, let's continue. Next, we take the number 3,311,365 and divide it by 2:
3,311,365 ÷ 2 = 1,655,682.5
If the quotient is a whole number, then 2 and 1,655,682.5 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 | 3,311,365 | |
| -1 | -3,311,365 |
Now, we try dividing 3,311,365 by 3:
3,311,365 ÷ 3 = 1,103,788.3333
If the quotient is a whole number, then 3 and 1,103,788.3333 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 | 3,311,365 | |
| -1 | -3,311,365 |
Let's try dividing by 4:
3,311,365 ÷ 4 = 827,841.25
If the quotient is a whole number, then 4 and 827,841.25 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 | 3,311,365 | |
| -1 | 3,311,365 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 41 | 145 | 205 | 557 | 1,189 | 2,785 | 5,945 | 16,153 | 22,837 | 80,765 | 114,185 | 662,273 | 3,311,365 |
| -1 | -5 | -29 | -41 | -145 | -205 | -557 | -1,189 | -2,785 | -5,945 | -16,153 | -22,837 | -80,765 | -114,185 | -662,273 | -3,311,365 |
