There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
A square of a prime.
Okay, whoever said that a number can only have an even number of factors IS Wrong Take a prime number and square it. If you square a prime number, the number you get will only have 3 factors. For example, if I squared the number 3, I would get 9. 9 only has three factors: 9, 3, 1 Any prime number squared has Three factors.
53 is a prime because its only factors are 1 and itself.
A square of any prime number, p has exactly three factors. They are 1, p and p^2.
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
All prime squares have three factors.
There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.
There are an infinite number of them. 8 has three prime factors, 30 is the first with three distinct prime factors.
No, no prime number has proper factors.
A square of a prime.
Any square of a prime number.
A composite number.
Squares of prime numbers have three factors.
3 is a prime number; its only factors are 1 and itself.
Squares of prime numbers are the only numbers with three factors, since there must be only one nontrivial divisor for a number to have three factors. That number must thus be prime.
