A composite number is a product of prime numbers.
So to answer your question. Yes as it is a product of two primes.
That is the prime 5
A prime number is a number that can only be divided by 1 and itself and no other whole number to give a whole number answer.
Any number that is a product of primes is a composite number.
Consider the prime factor tree:
3 and 79 are primes in that they can only be divided by themselves and 1 to give whole number answers.
But
Hear is another composite split into its prime factors
So the composite 638 is a product of the prime {2,11,29}
In that I quick search on the internet will lists of prime numbers. If you can it is a good idea to try and remember some of them. In England schools encourage the remembering the primes numbers up 97
