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 1,331,099, 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 | 1,331,099 | |
| -1 | -1,331,099 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,331,099.
Example:
1 x 1,331,099 = 1,331,099
and
-1 x -1,331,099 = 1,331,099
Notice both answers equal 1,331,099
With that explanation out of the way, let's continue. Next, we take the number 1,331,099 and divide it by 2:
1,331,099 ÷ 2 = 665,549.5
If the quotient is a whole number, then 2 and 665,549.5 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 | 1,331,099 | |
| -1 | -1,331,099 |
Now, we try dividing 1,331,099 by 3:
1,331,099 ÷ 3 = 443,699.6667
If the quotient is a whole number, then 3 and 443,699.6667 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 | 1,331,099 | |
| -1 | -1,331,099 |
Let's try dividing by 4:
1,331,099 ÷ 4 = 332,774.75
If the quotient is a whole number, then 4 and 332,774.75 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 | 1,331,099 | |
| -1 | 1,331,099 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 59 | 77 | 293 | 413 | 649 | 2,051 | 3,223 | 4,543 | 17,287 | 22,561 | 121,009 | 190,157 | 1,331,099 |
| -1 | -7 | -11 | -59 | -77 | -293 | -413 | -649 | -2,051 | -3,223 | -4,543 | -17,287 | -22,561 | -121,009 | -190,157 | -1,331,099 |
