The product of two prime numbers will be composite.
A composite number is the product of two or more prime numbers.
No not always because composite numbers can be the product of 2 or more prime factors
Composite
The product of two prime numbers is always a composite number, and it never is a prime number.
composite
When the numbers are relatively prime.
A composite number is the product of two or more prime numbers. A prime number has exactly two factors, 1 and the number itself; a composite number has at least one more factor than the two that a prime number has.
Prime numbers only have two factors, one and themselves. If you multiply two prime numbers together, the new number will also have the two prime numbers as factors, making it composite. Try it out. 5 and 7 are prime. 35 is composite.
When the numbers are relatively prime.
If the number is a product of two composite numbers, it must be 16, which is the product of 4 and 4. The prime factors of 16 are 2, 2, 2, and 2. The smallest composite number is 4, so the smallest possible product of two composite numbers is 4 x 4 = 16.
There are no two "last" composite numbers. Just as with prime numbers, and all numbers, they go on for ever and ever and ever and ever ... ... .
No, because a prime number that has only two factors, 1(which is niether prime nor composite) and itself(prime).
