Prime numbers:

  • Any natural number higher than 1 that is not the sum of two smaller natural numbers is referred to be a prime number.
  • A composite number is a natural number greater than one that is not prime.
  • For instance, the number 5 is prime because there are only two ways to write it as a product, 1 × 5 and 5 × 1.

Composite numbers:

  • Any positive integer that may be created by multiplying two other positive integers is referred to as a composite number.
  • It is, in other words, a positive integer that has at least one divisor besides itself and the number 1.
  • Every positive integer is either composite, prime, or the number 1, hence the numbers that are neither prime nor a unit are known as composite numbers.
  • For instance, the composite number 14 is created by multiplying the two smaller numbers 2 and 7.
  • The numerals 2 and 3 cannot be divided by anything other than themselves and one, hence they are not composite numbers either.

Therefore, the prime and composite numbers are as follows:

  1. (a) Prime
  2. (b) Prime
  3. (c) Composite
  4. (d) Prime
  5. (e) Composite
  6. (f) Composite
