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 3,225,649, 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 | 3,225,649 | |
| -1 | -3,225,649 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,225,649.
Example:
1 x 3,225,649 = 3,225,649
and
-1 x -3,225,649 = 3,225,649
Notice both answers equal 3,225,649
With that explanation out of the way, let's continue. Next, we take the number 3,225,649 and divide it by 2:
3,225,649 ÷ 2 = 1,612,824.5
If the quotient is a whole number, then 2 and 1,612,824.5 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 | 3,225,649 | |
| -1 | -3,225,649 |
Now, we try dividing 3,225,649 by 3:
3,225,649 ÷ 3 = 1,075,216.3333
If the quotient is a whole number, then 3 and 1,075,216.3333 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 | 3,225,649 | |
| -1 | -3,225,649 |
Let's try dividing by 4:
3,225,649 ÷ 4 = 806,412.25
If the quotient is a whole number, then 4 and 806,412.25 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 | 3,225,649 | |
| -1 | 3,225,649 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 79 | 133 | 307 | 553 | 1,501 | 2,149 | 5,833 | 10,507 | 24,253 | 40,831 | 169,771 | 460,807 | 3,225,649 |
| -1 | -7 | -19 | -79 | -133 | -307 | -553 | -1,501 | -2,149 | -5,833 | -10,507 | -24,253 | -40,831 | -169,771 | -460,807 | -3,225,649 |
