Question

Q.25. Which of the following is prime?​

Answer 1

Answer:

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

Answer 2

a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11).
