The number 30 is a perfect number. A perfect number is defined as a positive integer that is equal to the sum of its proper divisors, excluding itself. The proper divisors of 30 are 1, 2, 3, 5, 6, and 15, which sum to 30. However, it should be noted that 30 is actually classified as an abundant number because the sum of its proper divisors (1 + 2 + 3 + 5 + 6 + 15 = 32) is greater than 30.

Is 30 an abundant or deficient?
The number 30 is considered a deficient number. An abundant number is one where the sum of its proper divisors (excluding itself) is greater than the number itself, while a deficient number has a sum of proper divisors that is less than the number. The proper divisors of 30 are 1, 2, 3, 5, 6, and 15, which sum to 32. Since 32 is greater than 30, 30 is actually classified as an abundant number, not deficient.
Is 120 a deficient number?
No, 120 is not a deficient number; it is considered an abundant number. A deficient number is one where the sum of its proper divisors is less than the number itself. In the case of 120, the sum of its proper divisors (1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, and 60) is 186, which is greater than 120.
