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 1,177,969, 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 | 1,177,969 | |
| -1 | -1,177,969 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,177,969.
Example:
1 x 1,177,969 = 1,177,969
and
-1 x -1,177,969 = 1,177,969
Notice both answers equal 1,177,969
With that explanation out of the way, let's continue. Next, we take the number 1,177,969 and divide it by 2:
1,177,969 ÷ 2 = 588,984.5
If the quotient is a whole number, then 2 and 588,984.5 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 | 1,177,969 | |
| -1 | -1,177,969 |
Now, we try dividing 1,177,969 by 3:
1,177,969 ÷ 3 = 392,656.3333
If the quotient is a whole number, then 3 and 392,656.3333 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 | 1,177,969 | |
| -1 | -1,177,969 |
Let's try dividing by 4:
1,177,969 ÷ 4 = 294,492.25
If the quotient is a whole number, then 4 and 294,492.25 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 | 1,177,969 | |
| -1 | 1,177,969 |
If you did it right, you will end up with this table:
| 1 | 13 | 31 | 37 | 79 | 403 | 481 | 1,027 | 1,147 | 2,449 | 2,923 | 14,911 | 31,837 | 37,999 | 90,613 | 1,177,969 |
| -1 | -13 | -31 | -37 | -79 | -403 | -481 | -1,027 | -1,147 | -2,449 | -2,923 | -14,911 | -31,837 | -37,999 | -90,613 | -1,177,969 |
