A number can be classified as either a prime number or a composite number. Prime numbers have various applications in the field of cryptography, computer algorithms and mathematics. In this article, we will check if 6 is a prime number and how.
Factors of 63 are — 1,3,7,9,21 and 63 meaning it is not a prime number as all prime numbers have only two factors and the number itself. From the mentioned, we can clearly tell that 63 is not a prime number.
Listed below are methods to find if a number is prime or not.
In this method, we write down the divisors of the numbers and check if it satisfies the condition for prime numbers.
→ 63 is not a prime number.
If the number 63 is divisible by any number but 1 and 63 it is composite. The number 63 is divisible by numbers 3,7,9,21 clearly making it a composite number.
The prime numbers up to 100 are;
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,
53,59,61,67,71,73,79,83,89,97.
63 is not on the list, it is a composite number.
Prime factorization of 63
63 = 3×3×7 = 32×7
63 is being easily factored into smaller factors, clearly making it a composite number.
Listed below are mistakes one may commit when trying to figure if given number is prime or composite, be mindful of the same.
