WebExample 1: Find out if 928 is a prime number or not. Solution: The list of prime numbers from 1 to 1000 does not cover the number 928. 928 is not a prime number because it is an even number and is divisible by 2. 928 ÷ 2 = 464 This shows that 2 is a factor of 928 apart from 1 and 928, so it is not a prime number.
