The divisors of 101 are: 1, 101.
2,835 has 20 divisors.
120,000 has 70 proper divisors.
Since 11 is a prime number, its only divisors are 1 and itself.
64 has 7 divisors: 1 2 4 8 16 32 64.
Yes, it has divisors other that 1 and itself, e.g. 3,181. In fact by the divisibility condition, "The sum of the digits is divisible by 3, therefore the number itself is divisible by 3", clearly 543 is divisible by 3, i.e. 5+4+3 = 12/3 = 4 making it composite.
