All even numbers less than 20 are composite. find an even number less than 20 that is NOT composite. Explain in way the number is not composite.
9 and 15
Composite numbers greater than 20 and less than 30 are 21, 22, 24, 25, 26, 27, 28.
This question is impossible to answer because there are six composite numbers in that range, not five!
The odd composite numbers lower than 30 are:9 15 21 25 27
All of them except 31 and 37 which are prime numbers
All of the composite numbers less than 100 have factor pairs.
Literally every single even number less than 1000 is a composite number other than 2 which is prime.
49, 50, 51, 52, 54 and 55 are the composite numbers between 48 and 56.
What is the sum of the composite numbers less than 10?4 + 6 + 8 + 9 = 27
99 is one of them and all other numbers less than 100 that have more than two factors in them.
They are all composite.
They are: 4+6+8+9 = 27
It is: 4+6+8+9 = 27
All of them except for 23 which is a prime number
All composite numbers have more than two factors.
They are not because only numbers that have more than two factors are composite numbers.
For this type of question, you should search the Internet for a list of prime numbers. All the integers that are not prime numbers are composite. In this case, the relevant prime numbers are 101 and 103.
The list of composite numbers is infinite. They all have more than two factors.
Composite numbers less than 10 are 4, 6, 8 and 9. So, the sum is 4 + 6 + 8 + 9 = 27.
composite numbers are those that have more than 2 factors. all even numbers other than 2 are composite numbers and some odd numbers are composite numbers. numbers that are prime are the numbers that are not composite numbers i hope this answers your question :)
They are: 4+6 = 10 and including 8 = 18
