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 3,600,205, 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 | 3,600,205 | |
| -1 | -3,600,205 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,600,205.
Example:
1 x 3,600,205 = 3,600,205
and
-1 x -3,600,205 = 3,600,205
Notice both answers equal 3,600,205
With that explanation out of the way, let's continue. Next, we take the number 3,600,205 and divide it by 2:
3,600,205 ÷ 2 = 1,800,102.5
If the quotient is a whole number, then 2 and 1,800,102.5 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 | 3,600,205 | |
| -1 | -3,600,205 |
Now, we try dividing 3,600,205 by 3:
3,600,205 ÷ 3 = 1,200,068.3333
If the quotient is a whole number, then 3 and 1,200,068.3333 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 | 3,600,205 | |
| -1 | -3,600,205 |
Let's try dividing by 4:
3,600,205 ÷ 4 = 900,051.25
If the quotient is a whole number, then 4 and 900,051.25 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 | 3,600,205 | |
| -1 | 3,600,205 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 1,015 | 3,547 | 17,735 | 24,829 | 102,863 | 124,145 | 514,315 | 720,041 | 3,600,205 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -1,015 | -3,547 | -17,735 | -24,829 | -102,863 | -124,145 | -514,315 | -720,041 | -3,600,205 |
