Prime numbers list. List of prime numbers up to 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
What is the product of two composite numbers?
It always is, any product of two composite numbers is not a prime, and 1 is not a composite number. So the product of two composite numbers can never be a prime.

What are composite numbers between 11 and 19?
Between 11 and 19 we have 12,14,15,16,18 as composite numbers.
Is 2 a composite number?
Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself. Every composite number can be written as the product of two or more (not necessarily distinct) primes.
Is 17a composite number?
Is 17 a Composite Number? No, since 17 has only two factors, i.e. 1 and 17. In other words, 17 is not a composite number because 17 doesn’t have more than 2 factors.
Is 17 a prime or composite?
The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29. There are 25 prime numbers between 1 and 100. Prime numbers can continue well past 100.
Is 17 a composite number?
No, since 17 has only two factors, i.e. 1 and 17. In other words, 17 is not a composite number because 17 doesn’t have more than 2 factors.
Is 16 a composite number?
which is not prime (i.e., which has factors other than 1 and itself). The first few composite numbers (sometimes called “composites” for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, (OEIS A002808), whose prime decompositions are summarized in the following table.
Is 17 a prime or composite number?
The first 10 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29. There are 25 prime numbers between 1 and 100. Prime numbers can continue well past 100. For example, 21,577 is a prime number.

Which is a composite number other than itself?
A composite number is a whole number that can be divided evenly by numbers other than 1 or itself. A composite number n is a positive integer n>1 which is not prime (i.e., it can be divided by whole number other than 1 and itself).
What are numbers between 11 and 19 are composite numbers?
As even numbers are multiples of 2, between 11 andd 19 we have 12,14,16,18 as composite numbers among odd numbers 13,15,17 only 15 has factors other than 1 and itself.
Is the number 12 a prime or composite number?
We don’t consider ‘1’ as a composite number. 12 is a composite number because it can be divided by 1, 2, 3, 4, 6 and 12. So, the number ‘12’ has 6 factors. What are Coprime Numbers? The coprime-numbers or mutually primes or relatively primes are the two numbers which have only one common factor, which is 1.
Is the number 7 a prime or a composite number?
The number 7 is prime. In problem 2 above, the number 8 has four factors. The number 8 is composite. A prime number has only two factors: 1 and itself. A composite number has more than two factors. The number 1 is neither prime nor composite.
