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 1,160,665, 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 | 1,160,665 | |
| -1 | -1,160,665 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,160,665.
Example:
1 x 1,160,665 = 1,160,665
and
-1 x -1,160,665 = 1,160,665
Notice both answers equal 1,160,665
With that explanation out of the way, let's continue. Next, we take the number 1,160,665 and divide it by 2:
1,160,665 ÷ 2 = 580,332.5
If the quotient is a whole number, then 2 and 580,332.5 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 | 1,160,665 | |
| -1 | -1,160,665 |
Now, we try dividing 1,160,665 by 3:
1,160,665 ÷ 3 = 386,888.3333
If the quotient is a whole number, then 3 and 386,888.3333 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 | 1,160,665 | |
| -1 | -1,160,665 |
Let's try dividing by 4:
1,160,665 ÷ 4 = 290,166.25
If the quotient is a whole number, then 4 and 290,166.25 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 | 1,160,665 | |
| -1 | 1,160,665 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 47 | 55 | 235 | 449 | 517 | 2,245 | 2,585 | 4,939 | 21,103 | 24,695 | 105,515 | 232,133 | 1,160,665 |
| -1 | -5 | -11 | -47 | -55 | -235 | -449 | -517 | -2,245 | -2,585 | -4,939 | -21,103 | -24,695 | -105,515 | -232,133 | -1,160,665 |
