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 3,241,645, 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 | 3,241,645 | |
| -1 | -3,241,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,241,645.
Example:
1 x 3,241,645 = 3,241,645
and
-1 x -3,241,645 = 3,241,645
Notice both answers equal 3,241,645
With that explanation out of the way, let's continue. Next, we take the number 3,241,645 and divide it by 2:
3,241,645 ÷ 2 = 1,620,822.5
If the quotient is a whole number, then 2 and 1,620,822.5 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 | 3,241,645 | |
| -1 | -3,241,645 |
Now, we try dividing 3,241,645 by 3:
3,241,645 ÷ 3 = 1,080,548.3333
If the quotient is a whole number, then 3 and 1,080,548.3333 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 | 3,241,645 | |
| -1 | -3,241,645 |
Let's try dividing by 4:
3,241,645 ÷ 4 = 810,411.25
If the quotient is a whole number, then 4 and 810,411.25 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 | 3,241,645 | |
| -1 | 3,241,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 3,467 | 17,335 | 38,137 | 58,939 | 190,685 | 294,695 | 648,329 | 3,241,645 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -3,467 | -17,335 | -38,137 | -58,939 | -190,685 | -294,695 | -648,329 | -3,241,645 |
