No. That isn't possible: A prime number, by definition, has no smaller factors. A square number does have a smaller factor - the number that is squared.

All the numbers above 2 that are the squares of odd primes have exactly 3 factors: 1, the odd prime, and the odd prime squared. 4, 9, 25, 49, 81, 121,...

Any two prime numbers will be relatively prime. Numbers are relatively prime if they do not have any prime factors in common. Prime numbers have only themselves as prime factors, so all prime numbers are relatively prime to the others.

Products of prime numbers are composite numbers.

The opposite of prime numbers are composite numbers.

they are both numbers

The only prime numbers with squares less than 20 are 2 and 3 Numbers containing 2 squared : 4, 8, 12, 16 Numbers containing 3 squared : 9, 18

2(squared) times 163

2 squared 3 squared 5 or 180

It must be 81 because 9 squared is 81 and 9 is not a prime number whereas the other numbers are squared prime numbers.

2 x 32 = 18

4, 9, 25, 49, 121 and so on.

yes lots, the majority of numbers for example the numbers 10, 24 and 56 (there are lots more in between, and after)

A prime number is a positive integer with two factors: one and the number itself. A squared number is any integer multiplied by itself. With the exception of 1, all squared numbers are composite.
