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 3,247,945, 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 | 3,247,945 | |
| -1 | -3,247,945 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,247,945.
Example:
1 x 3,247,945 = 3,247,945
and
-1 x -3,247,945 = 3,247,945
Notice both answers equal 3,247,945
With that explanation out of the way, let's continue. Next, we take the number 3,247,945 and divide it by 2:
3,247,945 ÷ 2 = 1,623,972.5
If the quotient is a whole number, then 2 and 1,623,972.5 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 | 3,247,945 | |
| -1 | -3,247,945 |
Now, we try dividing 3,247,945 by 3:
3,247,945 ÷ 3 = 1,082,648.3333
If the quotient is a whole number, then 3 and 1,082,648.3333 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 | 3,247,945 | |
| -1 | -3,247,945 |
Let's try dividing by 4:
3,247,945 ÷ 4 = 811,986.25
If the quotient is a whole number, then 4 and 811,986.25 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 | 3,247,945 | |
| -1 | 3,247,945 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 61 | 115 | 305 | 463 | 1,403 | 2,315 | 7,015 | 10,649 | 28,243 | 53,245 | 141,215 | 649,589 | 3,247,945 |
| -1 | -5 | -23 | -61 | -115 | -305 | -463 | -1,403 | -2,315 | -7,015 | -10,649 | -28,243 | -53,245 | -141,215 | -649,589 | -3,247,945 |
