Lucy’s says that 15 is both a prime number and a composite number state weather you agree or disagree with Lucy and be sure to give a definition or either a prime or composite number to strengthen your argument
I disagree with Lucy's statement. The number 15 is not both a prime number and a composite number; it is only a composite number.
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In other words, it is a number that cannot be divided evenly by any other number except for 1 and itself. The first few prime numbers are 2, 3, 5, 7, 11, and so on.
A composite number, on the other hand, is a natural number greater than 1 that can be divided evenly by at least one other positive integer besides 1 and itself. In simpler terms, a composite number has more than two positive divisors. The number 15 can be divided evenly by 1, 3, 5, and 15, making it a composite number.
Since 15 has more than two positive divisors (1, 3, 5, and 15), it fits the definition of a composite number, but it does not fit the definition of a prime number. Therefore, Lucy's statement is incorrect.
