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 3,360,305, 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 | 3,360,305 | |
| -1 | -3,360,305 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,360,305.
Example:
1 x 3,360,305 = 3,360,305
and
-1 x -3,360,305 = 3,360,305
Notice both answers equal 3,360,305
With that explanation out of the way, let's continue. Next, we take the number 3,360,305 and divide it by 2:
3,360,305 ÷ 2 = 1,680,152.5
If the quotient is a whole number, then 2 and 1,680,152.5 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 | 3,360,305 | |
| -1 | -3,360,305 |
Now, we try dividing 3,360,305 by 3:
3,360,305 ÷ 3 = 1,120,101.6667
If the quotient is a whole number, then 3 and 1,120,101.6667 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 | 3,360,305 | |
| -1 | -3,360,305 |
Let's try dividing by 4:
3,360,305 ÷ 4 = 840,076.25
If the quotient is a whole number, then 4 and 840,076.25 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 | 3,360,305 | |
| -1 | 3,360,305 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 65 | 85 | 221 | 1,105 | 3,041 | 15,205 | 39,533 | 51,697 | 197,665 | 258,485 | 672,061 | 3,360,305 |
| -1 | -5 | -13 | -17 | -65 | -85 | -221 | -1,105 | -3,041 | -15,205 | -39,533 | -51,697 | -197,665 | -258,485 | -672,061 | -3,360,305 |
