Best Answer

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.
