Answer:
The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19 and 23, and we have a prime number chart if you need more.
If we can make it by multiplying other whole numbers it is a Composite Number.
Like this:
prime composite
2 is Prime, 3 is Prime, 4 is Composite (=2×2), 5 is Prime, and so on...
