Oh, what a happy little question! Prime numbers are like the stars in the night sky, shining brightly on their own - they can only be divided by 1 and themselves. Numbers like 2, 3, 5, and 7 are prime. Composite numbers are a bit more social, as they can be divided by more than just 1 and themselves. Numbers like 4, 6, 8, 9, and 10 are composite, but each one is special in its own way.
24 is composite because it can factored or split up as 24 = 3 * 8 for example. Prime numbers, such as 23, can not be split into factors.
The odd numbers are 101, 103, 105, 107, 109, etc. - just add two at a time. To include only composite numbers, look up a table of prime numbers, and delete those from the list.
The first two prime numbers add up to another prime number.
Please note that there are infinitely many prime numbers. An Internet search for "list of prime numbers" will quickly give you a list of prime numbers up to a certain point, for example here: http://en.wikipedia.org/wiki/List_of_prime_numbers Any integer greater than 1 that is not in the list of prime numbers is a composite number. (1 is considered neither a prime number, nor a composite number.)
Prime numbers go on forever.
All composite numbers have more than 2 factors but prime numbers have only 2 factors
Look up a table of prime numbers. All those numbers that are not prime, are composite - except 1, which is neither prime nor composite.
Look up a list of prime numbers (a Google search for "prime numbers" or "list of prime numbers" should do); every number (greater than 1) that is NOT a prime number is composite.
So the composite numbers won't get all bunched up.
Not necessarily. For example 15 and 16 are composite numbers. They add to 31, which is a prime number. Similarly, the composite numbers 20 and 21 add up to 41, which is a prime number.
All the multiples of 11 up to 100 except 11 itself which is a prime number
To distinguish them from prime numbers. Composite means "made up of various parts or elements." Prime numbers have one and only one factor pair. Composite numbers have a various number of factor pairs, but always more than one.
A composite number is made up of a product of prime numbers. It might be considered a non-prime number.
24 is composite because it can factored or split up as 24 = 3 * 8 for example. Prime numbers, such as 23, can not be split into factors.
The odd numbers are 101, 103, 105, 107, 109, etc. - just add two at a time. To include only composite numbers, look up a table of prime numbers, and delete those from the list.
You could try dividing by composite numbers but the number that you are testing is divisible by a composite number, then it will be divisible by a prime factor of that composite number and that prime factor will be smaller. It is always easier to work with smaller numbers.
No, there are only 25 prime numbers less than 100.........remember that 1 is classed as unity and is not a prime number and 2 is the only even prime number.
