A prime number is a number that is only divisible by 1 and itself. For example, 3 is a prime number because it can only be divided evenly by 1 and 3. However, 4 is not a prime number because it can be divided evenly by 1, 2, and 4. Prime numbers are important in mathematics because they can’t be made by multiplying other numbers together.
