Which one of the following numbers is the least prime number?a)2b)0c)1...
Explanation:
A prime number is a number that is greater than 1 and has no divisors other than 1 and itself. In other words, it cannot be divided evenly by any other number except for 1 and itself.
Let's analyze the options one by one to determine the least prime number.
a) 2:
The number 2 is the smallest prime number because it is greater than 1 and has no divisors other than 1 and itself. Therefore, option 'a' is a valid answer.
b) 0:
The number 0 is not a prime number because it does not meet the criteria of being greater than 1. It is a non-negative integer but not considered a prime number.
c) 1:
The number 1 is not a prime number because it only has one divisor, which is 1. Prime numbers must have exactly two divisors, 1 and itself. Therefore, 1 is not a prime number.
d) 3:
The number 3 is a prime number because it is greater than 1 and has exactly two divisors, 1 and 3. This means that it cannot be divided evenly by any other number.
Conclusion:
Among the given options, the least prime number is 2 (option 'a'). It is the smallest prime number because it is greater than 1 and has no divisors other than 1 and itself.
