Define Prime Numbers.

Select your answer for: Define Prime Numbers.
Show answer

Answer: C. Which can be divided by Number 1 & by itself Number

Explanation

Prime numbers are strictly defined as whole numbers greater than one with exactly two distinct divisors. The only positive divisors of any prime number are the number one and itself. Numbers having additional divisors besides one and themselves are classified as composite numbers. The number one is neither prime nor composite because it has only a single positive divisor. The sequence of prime numbers begins with two, three, five, seven, eleven, and thirteen. Every integer greater than one is either a prime number or a product of prime numbers.

Prime numbers form the foundational building blocks of all integer arithmetic in number theory. Modern computer security encryption systems rely on the difficulty of factoring large prime numbers. Educational mathematics curricula introduce prime numbers early to develop foundational divisor concepts. Option A suggests division by odd numbers which incorrectly includes composite odd integers. Option B proposes division by even numbers which incorrectly includes composite evens like four and six. Option D offers division by any number which describes all numbers rather than primes specifically.
