6, 8 and 10, among others.
That's an infinite list, starting with 6.
All numbers that have exactly two factors are prime numbers whereas composite numbers have more than two factors.
Prime squares have three factors. 4, 9, 25
4, 9, 25 and 49 They are squares of prime numbers.
A factor is a number or algebraic expression by which another is exactly divisible. Whole factors are whole numbers that are factors. In the equation 3 x 4 = 12, 3 and 4 are factors of 12.
Prime numbers have exactly two numbers. There is theoretically an infinite number of them.
8 10 12 and 13
4 and 9
Numbers with exactly three factors are squares of prime numbers.
Squares of prime numbers have exactly three factors.
4, 9 and 25.
2 4 6
Squares of prime numbers, like 4, 9 and 25.
4 (factors 1, 2 and 4) and 9 (factors 1, 3 and 9) are two examples.
Numbers with three factors are squares of primes. So: 4, 9, 25
Prime numbers have exactly two factors. 3 has exactly two factors: 1 and 3. So 3 is prime. Composite numbers have more than two factors. 4 is composite because it has three factors: 1, 2, and 4.
All numbers that are the square of primes have exactly 3 factors.
All numbers that have exactly two factors are prime numbers whereas composite numbers have more than two factors.
