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
No. The number 111 is composite.
As 1+1+1=3, 111 can be divided by 3 then it's a composite number
111 is a multiple of 3. Due to this, 111 is not prime and IS composite.
It's a composite - it can be divided by 3.
111 is a composite number. Composite numbers are any number that has more than two factors(one and itself). Therefore, since 3 and 37 are factors of 111 that makes it a composite number.
It is a composite number because it has more than two factors
111 is a composite number because it has more than two factors
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 81 is composite, 111 is prime.
555 is not prime. 555 = 3 * 5 * 37
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.
both composite
