Prime numbers and composite numbers
Prime number: Any positive integer (other than 1 and 0) that is divisible by 1 and itself is called a prime number. For example, 2, 3, 5, 7, 11, 13,… are prime number sequences.
Composite numbers: All the other positive numbers (4, 6, 8, 9, 10, 12, 14, 15,… ) other than 0 and 1 are called composite numbers.
1 and 0 are neither prime nor composite.
