Yes, this is well known. All integral multiples of any perfect, or abundant number must be an abundant number.
The number 24 is classified as an abundant number. An abundant number is one where the sum of its proper divisors (excluding itself) is greater than the number itself. For 24, the proper divisors are 1, 2, 3, 4, 6, and 8, which sum to 24, making it equal to the number itself. Therefore, since the sum of the proper divisors equals 24, it is not perfect; however, the total sum of divisors including 24 is 60, which is greater than 24, confirming it as abundant.
Yes.
