113 is a prime number. 111 and 115 are composites.
Composite
111 is composite. If the sum of the digits in the number is divisible by 3, then the number itself is. 1+1+1 = 3, therefore 111 is divisible by 3. 111/3=37 37 is prime, so the prime factorisation of 111 is 3x37.
No it is not a prime number. It is divisible by 1, 7, 111 and 777
No, it is not.

No. The number 111 is composite.
No. 111 = 3 * 37

If a number has only two factors then it is prime. For every natural number(except 1) we are sure about its two factors: 1 and the number itself. So the two factors we already know of 111 are 1 and 111. So if there exists some number which divides 111 evenly then 111 has more than two factors implies 111 is a composite number. 111 is not a prime number because it is divisible by 3.
111 is not a prime number. It is a composite number. A prime number is any number whose only factors are 1 and itself. 111's factors are 1, 3, 37, and 111. Well, it is prime if 111 is base 2 (binary) :P
As 1+1+1=3, 111 can be divided by 3 then it's a composite number
No it is not a prime number. It is divisible by 1, 7, 111 and 777
composite because 3*37 = 111
