Is 400 a prime number or a composite number?
400 is a composite number because it is divisible by more than two numbers. Because it ends in a 0, the divisibility rules indicate it is divisible by 2, 5, and 10. (It is also divisible by other numbers.) It is not a prime number because a prime number has exactly two factors, 1 and itself.

Yes, it is true that 2 is the only even prime number. All even numbers are evenly divisible by 2 (that is the definition of an even number). The number 2 is also divisible by 2, however, prime numbers, like all numbers, are evenly divisible by themselves, so that does not disqualify 2 from being a prime number.
Is 215 a prime number?

Which number is prime 4 or 10?
