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 3,270,965, 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 | 3,270,965 | |
| -1 | -3,270,965 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,270,965.
Example:
1 x 3,270,965 = 3,270,965
and
-1 x -3,270,965 = 3,270,965
Notice both answers equal 3,270,965
With that explanation out of the way, let's continue. Next, we take the number 3,270,965 and divide it by 2:
3,270,965 ÷ 2 = 1,635,482.5
If the quotient is a whole number, then 2 and 1,635,482.5 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 | 3,270,965 | |
| -1 | -3,270,965 |
Now, we try dividing 3,270,965 by 3:
3,270,965 ÷ 3 = 1,090,321.6667
If the quotient is a whole number, then 3 and 1,090,321.6667 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 | 3,270,965 | |
| -1 | -3,270,965 |
Let's try dividing by 4:
3,270,965 ÷ 4 = 817,741.25
If the quotient is a whole number, then 4 and 817,741.25 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 | 3,270,965 | |
| -1 | 3,270,965 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 47 | 155 | 235 | 449 | 1,457 | 2,245 | 7,285 | 13,919 | 21,103 | 69,595 | 105,515 | 654,193 | 3,270,965 |
| -1 | -5 | -31 | -47 | -155 | -235 | -449 | -1,457 | -2,245 | -7,285 | -13,919 | -21,103 | -69,595 | -105,515 | -654,193 | -3,270,965 |
