A **square-free integer** is an integer that is not divisible by the square of any prime number. In other words, a square-free integer cannot have any prime factor raised to a power greater than one in its prime factorization. For example: - The integer 30 is square-free because its prime factorization is \\(2^1 \\times 3^1 \\times 5^1\\); none of the prime factors are squared or higher.
