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 1,208,135, 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 | 1,208,135 | |
| -1 | -1,208,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,208,135.
Example:
1 x 1,208,135 = 1,208,135
and
-1 x -1,208,135 = 1,208,135
Notice both answers equal 1,208,135
With that explanation out of the way, let's continue. Next, we take the number 1,208,135 and divide it by 2:
1,208,135 ÷ 2 = 604,067.5
If the quotient is a whole number, then 2 and 604,067.5 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 | 1,208,135 | |
| -1 | -1,208,135 |
Now, we try dividing 1,208,135 by 3:
1,208,135 ÷ 3 = 402,711.6667
If the quotient is a whole number, then 3 and 402,711.6667 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 | 1,208,135 | |
| -1 | -1,208,135 |
Let's try dividing by 4:
1,208,135 ÷ 4 = 302,033.75
If the quotient is a whole number, then 4 and 302,033.75 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 | 1,208,135 | |
| -1 | 1,208,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 53 | 97 | 235 | 265 | 485 | 2,491 | 4,559 | 5,141 | 12,455 | 22,795 | 25,705 | 241,627 | 1,208,135 |
| -1 | -5 | -47 | -53 | -97 | -235 | -265 | -485 | -2,491 | -4,559 | -5,141 | -12,455 | -22,795 | -25,705 | -241,627 | -1,208,135 |
