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 1,326,479, 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 | 1,326,479 | |
| -1 | -1,326,479 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,326,479.
Example:
1 x 1,326,479 = 1,326,479
and
-1 x -1,326,479 = 1,326,479
Notice both answers equal 1,326,479
With that explanation out of the way, let's continue. Next, we take the number 1,326,479 and divide it by 2:
1,326,479 ÷ 2 = 663,239.5
If the quotient is a whole number, then 2 and 663,239.5 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 | 1,326,479 | |
| -1 | -1,326,479 |
Now, we try dividing 1,326,479 by 3:
1,326,479 ÷ 3 = 442,159.6667
If the quotient is a whole number, then 3 and 442,159.6667 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 | 1,326,479 | |
| -1 | -1,326,479 |
Let's try dividing by 4:
1,326,479 ÷ 4 = 331,619.75
If the quotient is a whole number, then 4 and 331,619.75 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 | 1,326,479 | |
| -1 | 1,326,479 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 23 | 49 | 77 | 107 | 161 | 253 | 539 | 749 | 1,127 | 1,177 | 1,771 | 2,461 | 5,243 | 8,239 | 12,397 | 17,227 | 27,071 | 57,673 | 120,589 | 189,497 | 1,326,479 |
| -1 | -7 | -11 | -23 | -49 | -77 | -107 | -161 | -253 | -539 | -749 | -1,127 | -1,177 | -1,771 | -2,461 | -5,243 | -8,239 | -12,397 | -17,227 | -27,071 | -57,673 | -120,589 | -189,497 | -1,326,479 |
