Do all even numbers are composite?
Solution :
Composite numbers are those numbers that are NOT prime numbers. These numbers have three or more factors which include 1 as well.
Eg: 4, 6, 8, 9, 10, 12, 15, 18, 21....and so on
Prime numbers are those numbers that are divisible by themselves and 1. No other number or numbers can divide them. These numbers have only two factors which include 1 as well.
Eg: 2, 3, 5, 7, 11, 13, 17....and so on.
2 is the only even prime number.
Therefore, All even numbers except 2 are composite numbers.
