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 1,204,165, 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 | 1,204,165 | |
| -1 | -1,204,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,204,165.
Example:
1 x 1,204,165 = 1,204,165
and
-1 x -1,204,165 = 1,204,165
Notice both answers equal 1,204,165
With that explanation out of the way, let's continue. Next, we take the number 1,204,165 and divide it by 2:
1,204,165 ÷ 2 = 602,082.5
If the quotient is a whole number, then 2 and 602,082.5 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 | 1,204,165 | |
| -1 | -1,204,165 |
Now, we try dividing 1,204,165 by 3:
1,204,165 ÷ 3 = 401,388.3333
If the quotient is a whole number, then 3 and 401,388.3333 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 | 1,204,165 | |
| -1 | -1,204,165 |
Let's try dividing by 4:
1,204,165 ÷ 4 = 301,041.25
If the quotient is a whole number, then 4 and 301,041.25 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 | 1,204,165 | |
| -1 | 1,204,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 37 | 115 | 185 | 283 | 851 | 1,415 | 4,255 | 6,509 | 10,471 | 32,545 | 52,355 | 240,833 | 1,204,165 |
| -1 | -5 | -23 | -37 | -115 | -185 | -283 | -851 | -1,415 | -4,255 | -6,509 | -10,471 | -32,545 | -52,355 | -240,833 | -1,204,165 |
