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.
composite because 3*37 = 111
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
555 is not prime. 555 = 3 * 5 * 37
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.
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
