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 3,243,205, 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 | 3,243,205 | |
| -1 | -3,243,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,243,205.
Example:
1 x 3,243,205 = 3,243,205
and
-1 x -3,243,205 = 3,243,205
Notice both answers equal 3,243,205
With that explanation out of the way, let's continue. Next, we take the number 3,243,205 and divide it by 2:
3,243,205 ÷ 2 = 1,621,602.5
If the quotient is a whole number, then 2 and 1,621,602.5 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 | 3,243,205 | |
| -1 | -3,243,205 |
Now, we try dividing 3,243,205 by 3:
3,243,205 ÷ 3 = 1,081,068.3333
If the quotient is a whole number, then 3 and 1,081,068.3333 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 | 3,243,205 | |
| -1 | -3,243,205 |
Let's try dividing by 4:
3,243,205 ÷ 4 = 810,801.25
If the quotient is a whole number, then 4 and 810,801.25 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 | 3,243,205 | |
| -1 | 3,243,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 4,877 | 24,385 | 34,139 | 92,663 | 170,695 | 463,315 | 648,641 | 3,243,205 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -4,877 | -24,385 | -34,139 | -92,663 | -170,695 | -463,315 | -648,641 | -3,243,205 |
