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 3,246,115, 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 | 3,246,115 | |
| -1 | -3,246,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,246,115.
Example:
1 x 3,246,115 = 3,246,115
and
-1 x -3,246,115 = 3,246,115
Notice both answers equal 3,246,115
With that explanation out of the way, let's continue. Next, we take the number 3,246,115 and divide it by 2:
3,246,115 ÷ 2 = 1,623,057.5
If the quotient is a whole number, then 2 and 1,623,057.5 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 | 3,246,115 | |
| -1 | -3,246,115 |
Now, we try dividing 3,246,115 by 3:
3,246,115 ÷ 3 = 1,082,038.3333
If the quotient is a whole number, then 3 and 1,082,038.3333 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 | 3,246,115 | |
| -1 | -3,246,115 |
Let's try dividing by 4:
3,246,115 ÷ 4 = 811,528.75
If the quotient is a whole number, then 4 and 811,528.75 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 | 3,246,115 | |
| -1 | 3,246,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 61 | 145 | 305 | 367 | 1,769 | 1,835 | 8,845 | 10,643 | 22,387 | 53,215 | 111,935 | 649,223 | 3,246,115 |
| -1 | -5 | -29 | -61 | -145 | -305 | -367 | -1,769 | -1,835 | -8,845 | -10,643 | -22,387 | -53,215 | -111,935 | -649,223 | -3,246,115 |
