Question: 1 / 2700

Which of the following is NOT a prime number?

1

2

3

4

A prime number is defined as a natural number greater than 1 that has no positive divisors other than 1 and itself. This means that prime numbers can only be divided evenly by 1 and the number itself without leaving a remainder.

The number 1 is not considered a prime number because it does not meet the requirement of being greater than 1. The numbers 2 and 3 are both prime; 2 can only be divided by 1 and 2, while 3 can only be divided by 1 and 3 without yielding a remainder.

The number 4, however, is not a prime number because it has divisors other than 1 and itself. Specifically, 4 can be divided by 1, 2, and 4. Since it has a divisor that is not itself or 1, it does not qualify as a prime number. Thus, among the options provided, 4 is the correct answer as it is not a prime number.
