Is 6 a Prime Number?
Prime numbers define those numbers that have 2 factors (1 and number itself). These numbers can be used in computer security or cryptography, designing computer algorithms, etc. We will know more about Prime numbers and check whether 6 is a prime number or not.
Is 6 a Prime Number?
Numbers can be either prime or composite. 6 is not a prime number, since factors of 6 are 1,2,3 and 6. That means it is not a prime number. So, we can say that 6 is a composite number.
Why is 6 a Prime Number?
We will now check through various methods that if 6 is a prime number or not. Let’s proceed.
- Counting Divisors Method
- Divisibility Test
- Prime Number Chart
- Prime Factorization Method
Using the Counting Divisors Method
The only condition this method involves is that a particular number is prime if and only if it has two distinct integers as its divisors. In case of 6, the distinct divisors are: 1,2,3, and 6. Hence, there exist more than two divisors of 6.
Hence, 6 is not prime.
Using the Divisibility Test Method
In the divisibility method, we have to check 6 with different numbers whether 6 is divisible or not. The rule is, if 6 is divisible by any number that falls between 2 and the square root of 6 itself, it is composite.
Testing the same in case of 6:
Step 1: Checking divisibility by 2
Any even number is divisible by 2. Also, the square root of 6 is less than 3, so no need to check divisibility greater than 2.
6/2 =3. So, 6 is perfectly divisible by 2.
We can conclude that 6 is not a prime number and 6 is divisible by numbers other than 1 and 6.
Using Prime Number Chart
The list of prime numbers up to 30 are → 2,3,5,7,11,13,17,19, 23,29
Following the above chart for reference, we can see that 6 is not in the list. Hence, 6 is not a prime number
Using the Prime Factorization Method
Prime factorization of 6
6 = 2×3
6 is being easily factored into smaller factors, clearly making it a composite number.
Common Mistakes to Avoid When Determining 6 is a Prime Number
Wrong concept of Prime numbers can lead to mathematical errors. So, let us see some common error which we should avoid making.
Mistake 1
Some students assume that all the odd numbers are prime.
All the odd numbers are not prime numbers, but all the prime numbers are odd numbers. Check before assuming.
