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 3,261,115, 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 | 3,261,115 | |
| -1 | -3,261,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,261,115.
Example:
1 x 3,261,115 = 3,261,115
and
-1 x -3,261,115 = 3,261,115
Notice both answers equal 3,261,115
With that explanation out of the way, let's continue. Next, we take the number 3,261,115 and divide it by 2:
3,261,115 ÷ 2 = 1,630,557.5
If the quotient is a whole number, then 2 and 1,630,557.5 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 | 3,261,115 | |
| -1 | -3,261,115 |
Now, we try dividing 3,261,115 by 3:
3,261,115 ÷ 3 = 1,087,038.3333
If the quotient is a whole number, then 3 and 1,087,038.3333 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 | 3,261,115 | |
| -1 | -3,261,115 |
Let's try dividing by 4:
3,261,115 ÷ 4 = 815,278.75
If the quotient is a whole number, then 4 and 815,278.75 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 | 3,261,115 | |
| -1 | 3,261,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 65 | 143 | 715 | 4,561 | 22,805 | 50,171 | 59,293 | 250,855 | 296,465 | 652,223 | 3,261,115 |
| -1 | -5 | -11 | -13 | -55 | -65 | -143 | -715 | -4,561 | -22,805 | -50,171 | -59,293 | -250,855 | -296,465 | -652,223 | -3,261,115 |
