If the integers of the number ad up to a number divisible by 3, the whole number is divisible by 3. 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.
69 is composite 1,69,3,23 are the factors.
It is prime.
prime
No, it is a prime.
It's composite because you can divide it by three.
Not necessarily. The prime factorization of the composite number 10 is 2 x 5. Composite numbers have three or more factors.
If it has two factors, it's prime. If it has more than two, it's composite.
129 is divisible by three, hence it is a composite number.
By using the divisibility rule for 3, we find that 117 is divisible by 3. That makes it composite.
I would say composite cos it can't be prime. prime is no which can only divide to aone nd it self but 63 can divide by 3!!!!!!!!!
198 is composite because it has three or more factors.
It is composite because you can multiply 3*11 to get 33.
