Any square of a Prime number. For example, 5*5 = 25 has the factors 1, 5, 25. If you square any other prime number, call it "p", the factors of the result are 1, p, p square.
there are only 2 factors because 3 is a prime number: the factors are 1 and 3
3 is a prime number. It is only evenly divisible by itself and one.The factors of 9 are: 1, 3, and 9.The only prime factor of 9 is: 3.

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.
A factor is a number that can evenly be divided into another number. Any number can be divided by one and itself. Numbers that can only be divided by one and themselves are called prime numbers. The number one and the number itself are factors of the number.Hence its factors are 1 and 3 itself.
they are called numbers with 3 factors
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.
The number 3 is a prime number because 1 and 3 is its only factors. A prime number has only two factors, in this case 1 and 3 are the factors. 17,11,7 and 13 are examples of prime numbers.
3 is a prime number because it has exactly two distinct factors. The only factors of a prime number are 1 and itself. The only factors of 3 are 1 and 3, so it is a prime number.
3 is a prime number because its only factors are 1 and 3. A prime number is a number that's factors are 1 and itself.
A compound number has 3 or more factors, two of the factors being 1 and the number itself.
3 is a prime number. A prime number is a product that only has 2 factors; 1 and itself. So the factors of 3 are 1,3.

A prime number has only 2 factors, 1 and itself.
3 is prime number so its only factors are 1 and itself. ^_^
A prime square
36,201 is not a prime number because 3 is one of its factors. 3 is one of the factors of any number whose digits add up to 3 or a multiple of 3. The only prime number with 3 as one of its factors is the number 3.
