Yes, it can. Examples are 2 and 5 to make 10 and 2 and 7 to make 14. If your question was if they could make an even Prime number, the answer is no. Two is the only even prime number.
There are an infinite amount of such numbers.
The product of two prime numbers will be composite.
No, the product of two prime numbers is unique.
two prime numbers whose product is 141 = 3 & 47
The product of two prime numbers is always a composite number, and it never is a prime number.
There are an infinite amount of such numbers.
Without knowing what the product is, it will be difficult to help. Presumably, you can tell the difference between even and odd numbers. If you are trying to predict, the product of two evens is even, the product of two odds is odd and the product of an even and an odd is even.
The product of two prime numbers will be composite.
It is impossible for the product of two prime numbers to be prime. It is impossible for the sum of two prime numbers to be prime as long as one of the numbers isn't 2.
No, the product of two prime numbers is unique.
The LCM of two numbers is one of the numbers when one of the numbers is a multiple of the other. The LCM of two numbers is the product of the numbers when they are relatively prime. In all other cases (like consecutive even numbers that aren't 2 and 4) the LCM is as you describe.
The product of any two numbers, neither of which is 1, is never a prime number.
two prime numbers whose product is 141 = 3 & 47
A composite number is the product of two or more prime numbers.
Not all the time, 11 x 3 = 33
The product of two prime numbers is always a composite number, and it never is a prime number.
