When is product of 2 prime numbers a prime number?
The product of two prime numbers is always a composite number, and it never is a prime number.
Can you list two composite numbers whose product is prime?
No, because a prime number that has only two factors, 1(which is niether prime nor composite) and itself(prime).
Is the product of 2 numbers a prime number?
The product of two numbers could be either a composite number or a prime number. If one of those numbers is 1 and the other is a prime number, the result is that prime number. If neither number is 1, the product of the two numbers will be a composite number. If one of those numbers is 1 and the other is not a prime number, the product will not be a prime number. So, in most cases, it will be a composite number.
The product of two primes?
Product of two prime numbers is a composite number. e.g. 2 x 3 = 6, 3 x 17 = 51 etc. But, why the result is a composite number? Definition of composite number makes it much clear: A number which can be expressed as the product of prime numbers is called a composite number. Also, it has more than two factors. So, product of two primes is a composite number.
Which numbers are not composite numbers?
Composite numbers have more than two factors. So, the numbers which have two or less than two factors are not composite numbers. Numbers which have exactly two factors are prime numbers. 1 is an exceptional case because it is neither prime nor composite since it has only one factor which is 1.
Are all composite numbers the product of two prime number?
No not always because composite numbers can be the product of 2 or more prime factors
What is a product of a prime number?
A composite number is the product of two or more prime numbers.
When is product of 2 prime numbers a prime number?
The product of two prime numbers is always a composite number, and it never is a prime number.
What do you call the product of any two prime numbers?
Composite
When two composite numbers are multiplied together will the product be a prime number or a composite number?
composite
What conditions is the LCM of two composite numbers simply the product of the two numbers?
When the numbers are relatively prime.
How prime numbers and composite numbers related?
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.
Why the product of two prime numbers is not prime?
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.
I am the product of two composite numbers and am between 11 and 17. What are the prime numbers that I am made of?
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.
Under what conditions is the LCM of two composite numbers simply the product of the two numbers?
When the numbers are relatively prime.
What is the product of the last two composite numbers?
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 ... ... .
Can you list two composite numbers whose product is prime?
No, because a prime number that has only two factors, 1(which is niether prime nor composite) and itself(prime).
