Explanation of number 18 Prime Factorization
Prime Factorization of 18 is expressing 18 as the product of prime factors. In other words, it is finding which prime numbers should be multiplied together to make 18.
Since number 18 is a Composite number (not Prime) we can do its Prime Factorization.
To get a list of all Prime Factors of 18, we have to iteratively divide 18 by the smallest prime number possible until the result equals 1.
Here is the complete solution of finding Prime Factors of 18:
The smallest Prime Number which can divide 18 without a remainder is 2. So the first calculation step would look like:
18 ÷ 2 = 9
Now we repeat this action until the result equals 1:
9 ÷ 3 = 3
3 ÷ 3 = 1
Now we have all the Prime Factors for number 18. It is: 2, 3, 3
Or you may also write it in exponential form: 2 × 32
