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 17,690,777, 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 | 17,690,777 | |
-1 | -17,690,777 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 17,690,777.
Example:
1 x 17,690,777 = 17,690,777
and
-1 x -17,690,777 = 17,690,777
Notice both answers equal 17,690,777
With that explanation out of the way, let's continue. Next, we take the number 17,690,777 and divide it by 2:
17,690,777 ÷ 2 = 8,845,388.5
If the quotient is a whole number, then 2 and 8,845,388.5 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 | 17,690,777 | |
-1 | -17,690,777 |
Now, we try dividing 17,690,777 by 3:
17,690,777 ÷ 3 = 5,896,925.6667
If the quotient is a whole number, then 3 and 5,896,925.6667 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 | 17,690,777 | |
-1 | -17,690,777 |
Let's try dividing by 4:
17,690,777 ÷ 4 = 4,422,694.25
If the quotient is a whole number, then 4 and 4,422,694.25 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 | 17,690,777 | |
-1 | 17,690,777 |
If you did it right, you will end up with this table:
1 | 13 | 1,360,829 | 17,690,777 |
-1 | -13 | -1,360,829 | -17,690,777 |
