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 3,288,857, 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 | 3,288,857 | |
| -1 | -3,288,857 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,288,857.
Example:
1 x 3,288,857 = 3,288,857
and
-1 x -3,288,857 = 3,288,857
Notice both answers equal 3,288,857
With that explanation out of the way, let's continue. Next, we take the number 3,288,857 and divide it by 2:
3,288,857 ÷ 2 = 1,644,428.5
If the quotient is a whole number, then 2 and 1,644,428.5 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 | 3,288,857 | |
| -1 | -3,288,857 |
Now, we try dividing 3,288,857 by 3:
3,288,857 ÷ 3 = 1,096,285.6667
If the quotient is a whole number, then 3 and 1,096,285.6667 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 | 3,288,857 | |
| -1 | -3,288,857 |
Let's try dividing by 4:
3,288,857 ÷ 4 = 822,214.25
If the quotient is a whole number, then 4 and 822,214.25 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 | 3,288,857 | |
| -1 | 3,288,857 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 109 | 143 | 211 | 1,199 | 1,417 | 2,321 | 2,743 | 15,587 | 22,999 | 30,173 | 252,989 | 298,987 | 3,288,857 |
| -1 | -11 | -13 | -109 | -143 | -211 | -1,199 | -1,417 | -2,321 | -2,743 | -15,587 | -22,999 | -30,173 | -252,989 | -298,987 | -3,288,857 |
