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 3,316,105, 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 | 3,316,105 | |
| -1 | -3,316,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,316,105.
Example:
1 x 3,316,105 = 3,316,105
and
-1 x -3,316,105 = 3,316,105
Notice both answers equal 3,316,105
With that explanation out of the way, let's continue. Next, we take the number 3,316,105 and divide it by 2:
3,316,105 ÷ 2 = 1,658,052.5
If the quotient is a whole number, then 2 and 1,658,052.5 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 | 3,316,105 | |
| -1 | -3,316,105 |
Now, we try dividing 3,316,105 by 3:
3,316,105 ÷ 3 = 1,105,368.3333
If the quotient is a whole number, then 3 and 1,105,368.3333 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 | 3,316,105 | |
| -1 | -3,316,105 |
Let's try dividing by 4:
3,316,105 ÷ 4 = 829,026.25
If the quotient is a whole number, then 4 and 829,026.25 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 | 3,316,105 | |
| -1 | 3,316,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 3,001 | 15,005 | 39,013 | 51,017 | 195,065 | 255,085 | 663,221 | 3,316,105 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -3,001 | -15,005 | -39,013 | -51,017 | -195,065 | -255,085 | -663,221 | -3,316,105 |
