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 1,336,489, 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 | 1,336,489 | |
| -1 | -1,336,489 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,336,489.
Example:
1 x 1,336,489 = 1,336,489
and
-1 x -1,336,489 = 1,336,489
Notice both answers equal 1,336,489
With that explanation out of the way, let's continue. Next, we take the number 1,336,489 and divide it by 2:
1,336,489 ÷ 2 = 668,244.5
If the quotient is a whole number, then 2 and 668,244.5 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 | 1,336,489 | |
| -1 | -1,336,489 |
Now, we try dividing 1,336,489 by 3:
1,336,489 ÷ 3 = 445,496.3333
If the quotient is a whole number, then 3 and 445,496.3333 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 | 1,336,489 | |
| -1 | -1,336,489 |
Let's try dividing by 4:
1,336,489 ÷ 4 = 334,122.25
If the quotient is a whole number, then 4 and 334,122.25 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 | 1,336,489 | |
| -1 | 1,336,489 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 17 | 77 | 119 | 187 | 1,021 | 1,309 | 7,147 | 11,231 | 17,357 | 78,617 | 121,499 | 190,927 | 1,336,489 |
| -1 | -7 | -11 | -17 | -77 | -119 | -187 | -1,021 | -1,309 | -7,147 | -11,231 | -17,357 | -78,617 | -121,499 | -190,927 | -1,336,489 |
