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 16,242,359, 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 | 16,242,359 | |
| -1 | -16,242,359 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,242,359.
Example:
1 x 16,242,359 = 16,242,359
and
-1 x -16,242,359 = 16,242,359
Notice both answers equal 16,242,359
With that explanation out of the way, let's continue. Next, we take the number 16,242,359 and divide it by 2:
16,242,359 ÷ 2 = 8,121,179.5
If the quotient is a whole number, then 2 and 8,121,179.5 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 | 16,242,359 | |
| -1 | -16,242,359 |
Now, we try dividing 16,242,359 by 3:
16,242,359 ÷ 3 = 5,414,119.6667
If the quotient is a whole number, then 3 and 5,414,119.6667 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 | 16,242,359 | |
| -1 | -16,242,359 |
Let's try dividing by 4:
16,242,359 ÷ 4 = 4,060,589.75
If the quotient is a whole number, then 4 and 4,060,589.75 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 | 16,242,359 | |
| -1 | 16,242,359 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 97 | 133 | 679 | 1,259 | 1,843 | 8,813 | 12,901 | 23,921 | 122,123 | 167,447 | 854,861 | 2,320,337 | 16,242,359 |
| -1 | -7 | -19 | -97 | -133 | -679 | -1,259 | -1,843 | -8,813 | -12,901 | -23,921 | -122,123 | -167,447 | -854,861 | -2,320,337 | -16,242,359 |
