Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.

No 5291 is not a prime using 2 numbers. It is a prime using three numbers.
The premise of your questions is false: NOT every number is a prime number.
A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.
30 has three prime numbers and is a factor of 60.
