How are two prime numbers related to each other?
Two prime numbers are always coprime to each other. Each composite number can be factored into prime factors and individually all of these are unique in nature. A prime number has two factors only. A composite number has more than two factors. It can be divided by 1 and the number itself. For example, 2 is divisible by 1 and 2.
Can a number not be a prime number?
Any number which is not prime can be written as the product of prime numbers: we simply keep dividing it into more parts until all factors are prime. For example, Now 2, 3 and 7 are prime numbers and can’t be divided further. The product 2 × 2 × 3 × 7 is called the prime factorisation of 84, and 2, 3 and 7 are its prime factors.
