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 16,755,991, 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 | 16,755,991 | |
-1 | -16,755,991 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 16,755,991.
Example:
1 x 16,755,991 = 16,755,991
and
-1 x -16,755,991 = 16,755,991
Notice both answers equal 16,755,991
With that explanation out of the way, let's continue. Next, we take the number 16,755,991 and divide it by 2:
16,755,991 ÷ 2 = 8,377,995.5
If the quotient is a whole number, then 2 and 8,377,995.5 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 | 16,755,991 | |
-1 | -16,755,991 |
Now, we try dividing 16,755,991 by 3:
16,755,991 ÷ 3 = 5,585,330.3333
If the quotient is a whole number, then 3 and 5,585,330.3333 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 | 16,755,991 | |
-1 | -16,755,991 |
Let's try dividing by 4:
16,755,991 ÷ 4 = 4,188,997.75
If the quotient is a whole number, then 4 and 4,188,997.75 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 | 16,755,991 | |
-1 | 16,755,991 |
If you did it right, you will end up with this table:
1 | 7 | 49 | 341,959 | 2,393,713 | 16,755,991 |
-1 | -7 | -49 | -341,959 | -2,393,713 | -16,755,991 |
