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. The largest prime number between 18 and 24 is 23.
Many prime numbers and many composite numbers.
The largest single digit composite number is 9. The largest prime number is 17 million digits long. The definition of a composite number is any number that has at least one positive divisor other than one or the number itself (it is not a prime number). The largest composite digit is therefore longer than the largest prime number by at leaf +1.
97A 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. 97 is the largest 2 digit prime number.
97 and 4
The largest staircase comosite largest staircase composite is the number 2223 because 1 is not counted as a prime so the 1 digit prime is 2, the smalles 2 digit prime is 11 and smallest 3 digit prime is 101

Each composite number has its own unique prime factorization. The largest number in that factorization would be the largest prime factor. It will never be more than half of the original number.
97A 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. 97 is the largest 2 digit prime number.

47 - 12 = 35
The largest staircase comosite largest staircase composite is the number 2223 because 1 is not counted as a prime so the 1 digit prime is 2, the smalles 2 digit prime is 11 and smallest 3 digit prime is 101
99 is the largest composite number less than 100: its prime factorisation is 3 x 3 x 11
47 is the largest prime number between 20 and 50.
No, twin primes are pairs of prime numbers that have only one number between them which is a composite number. For example, (3, 5) and (11, 13) are twin prime pairs with the composite number 4 and 12 respectively between them.
Prime numbers have two factors. Composite numbers have more than two.
21 is not a prime number.
