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 16,276,559, 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 | 16,276,559 | |
| -1 | -16,276,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,276,559.
Example:
1 x 16,276,559 = 16,276,559
and
-1 x -16,276,559 = 16,276,559
Notice both answers equal 16,276,559
With that explanation out of the way, let's continue. Next, we take the number 16,276,559 and divide it by 2:
16,276,559 ÷ 2 = 8,138,279.5
If the quotient is a whole number, then 2 and 8,138,279.5 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 | 16,276,559 | |
| -1 | -16,276,559 |
Now, we try dividing 16,276,559 by 3:
16,276,559 ÷ 3 = 5,425,519.6667
If the quotient is a whole number, then 3 and 5,425,519.6667 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 | 16,276,559 | |
| -1 | -16,276,559 |
Let's try dividing by 4:
16,276,559 ÷ 4 = 4,069,139.75
If the quotient is a whole number, then 4 and 4,069,139.75 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 | 16,276,559 | |
| -1 | 16,276,559 |
If you did it right, you will end up with this table:
| 1 | 13 | 19 | 37 | 137 | 169 | 247 | 481 | 703 | 1,781 | 2,603 | 3,211 | 5,069 | 6,253 | 9,139 | 23,153 | 33,839 | 65,897 | 96,311 | 118,807 | 439,907 | 856,661 | 1,252,043 | 16,276,559 |
| -1 | -13 | -19 | -37 | -137 | -169 | -247 | -481 | -703 | -1,781 | -2,603 | -3,211 | -5,069 | -6,253 | -9,139 | -23,153 | -33,839 | -65,897 | -96,311 | -118,807 | -439,907 | -856,661 | -1,252,043 | -16,276,559 |
