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 1,170,065, 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 | 1,170,065 | |
| -1 | -1,170,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,170,065.
Example:
1 x 1,170,065 = 1,170,065
and
-1 x -1,170,065 = 1,170,065
Notice both answers equal 1,170,065
With that explanation out of the way, let's continue. Next, we take the number 1,170,065 and divide it by 2:
1,170,065 ÷ 2 = 585,032.5
If the quotient is a whole number, then 2 and 585,032.5 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 | 1,170,065 | |
| -1 | -1,170,065 |
Now, we try dividing 1,170,065 by 3:
1,170,065 ÷ 3 = 390,021.6667
If the quotient is a whole number, then 3 and 390,021.6667 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 | 1,170,065 | |
| -1 | -1,170,065 |
Let's try dividing by 4:
1,170,065 ÷ 4 = 292,516.25
If the quotient is a whole number, then 4 and 292,516.25 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 | 1,170,065 | |
| -1 | 1,170,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 47 | 65 | 235 | 383 | 611 | 1,915 | 3,055 | 4,979 | 18,001 | 24,895 | 90,005 | 234,013 | 1,170,065 |
| -1 | -5 | -13 | -47 | -65 | -235 | -383 | -611 | -1,915 | -3,055 | -4,979 | -18,001 | -24,895 | -90,005 | -234,013 | -1,170,065 |
