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 12,976,559, 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 | 12,976,559 | |
| -1 | -12,976,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,976,559.
Example:
1 x 12,976,559 = 12,976,559
and
-1 x -12,976,559 = 12,976,559
Notice both answers equal 12,976,559
With that explanation out of the way, let's continue. Next, we take the number 12,976,559 and divide it by 2:
12,976,559 ÷ 2 = 6,488,279.5
If the quotient is a whole number, then 2 and 6,488,279.5 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 | 12,976,559 | |
| -1 | -12,976,559 |
Now, we try dividing 12,976,559 by 3:
12,976,559 ÷ 3 = 4,325,519.6667
If the quotient is a whole number, then 3 and 4,325,519.6667 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 | 12,976,559 | |
| -1 | -12,976,559 |
Let's try dividing by 4:
12,976,559 ÷ 4 = 3,244,139.75
If the quotient is a whole number, then 4 and 3,244,139.75 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 | 12,976,559 | |
| -1 | 12,976,559 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 109 | 149 | 799 | 1,853 | 2,533 | 5,123 | 7,003 | 16,241 | 87,091 | 119,051 | 276,097 | 763,327 | 12,976,559 |
| -1 | -17 | -47 | -109 | -149 | -799 | -1,853 | -2,533 | -5,123 | -7,003 | -16,241 | -87,091 | -119,051 | -276,097 | -763,327 | -12,976,559 |
