Greater than one, numbers are either composite or prime, never both.

Are all numbers composite explain?

not all numbers are composite cause theres also prime numbers bro.

Is 36 and 62 prime or composite?

They are both composite because they are even. They are composite numbers because 36 can be formed by 6x6 and 72 can be formed by 6x6x2. Since prime numbers means that they are only divisible by 1 and itself, the numbers are not prime numbers. Also, any number greater than 1 is either a composite or prime number, so they are composite numbers.

What makes prime numbers and composite numbers related?

Prime numbers are related with composite numbers as they are both natural numbers and real numbers and also every composite number is a product of prime numbers due to which they are related with each other.For example 24=[2] [2] [3] [2].Here 24 is a composite number,real number and natural number and 2,2,3,2 are prime numbers and also they are real and natural numbers

Is the addition of two composite numbers also a composite number?

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.

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.

Do prime numbers have to be odd and composite numbers have to be even?

No. All prime numbers except for the number 2 are odd. However, most odd numbers are composite numbers. All even numbers greater than 2 are composite numbers. So, prime numbers do not need to be odd, since one prime number is even. Also, composite numbers do not need to be even.Here are some composite odd numbers:9 = 3 x 333 = 3 x 1175 = 5 x 15

Is the sum of two composite numbers also composite?

Not always as for example 20+9 = 29 which is a prime number

What are the uses of prime and composite numbers?

All composite numbers have prime factors and these are used to find the highest common factor of 2 or more numbers and they are also used in finding the lowest common multiple of 2 or more numbers. Composite numbers have 2 or more factors while prime numbers have only 2 factors which are themselves and one

Are all square numbers also composite numbers explain?

Every square number (except 1) is composite. Prime numbers only have two factors, one and the numbers themselves. Since square numbers also have at least the square roots as factors, they have to be composite.

What does prime factorization tell you about numbers?

It tells you if a number is prime or composite and it also gives you a few factors of the number.

Are all composite numbers also even numbers?

No, some composite numbers are odd. The smallest composite odd numbers are 9, 15, 21, 25, and 27. Not all even numbers are composite either. There's only one even number that's prime, which is 2.

Is the sum of two prime numbers can be composite?

Not always, for example 2 + 3 = 5 where 5 is also a prime number.

Is 44 a composite or prime?

In addition to '1' and itself, the numbers 2, 4, 11, and 22 also go into 44; so it's composite.

What is the sum of the first four composite numbers?

You can figure out the "composite numbers" from any table of primes - all the positive integers that are not prime numbers are composite (the number one should also be excluded). The first four composite numbers are:4, 6, 8, 9

Why do you need to know about prime and composite numbers?

If you know a number is composite, then you also know that it can be factored into more factors than just 1 and itself. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.

What does composite mean for beginners?

Composite numbers are integers or whole numbers that contain more than two factors in them. Prime numbers are also integers but only have two factors which are themselves and one.

Does every composite number only have two prime factors?

no, because a composite number can be found by multiplying three prime numbers. 3*2*5 = 30, and 30 is a composite number and also has 3 prime factors. Every prime number has 1 prime factor by the way, itself. 1 is neither prime nor composite.

What makes a number not prime or composite?

0 and 1 (and -1) are the only integers which are not prime nor composite. All non-integral numbers are also non-prime and non-composite. This is because the property is not defined for such numbers.

Do composite numbers include 1 and itself?

No, those are prime numbers. Composite numbers can have besides 1 and itself. For example, let's say the number is 35. You can multiply 1 and 35, but you can also say 5 multiplied by 7. That is composite.

Is the number 2.9 centimeters composite or prime?

The question doesn't apply to mixed numbers, like 2.9. A mixed number is neither one. Also, "2.9 centimeters" is not a number; it's a length. Prime and composite numbers have no units. They're just bare numbers. 29 is a prime number.

Composite numbers between 30 and 40?

The composite numbers between 30 and 40 are: 32, 33, 34, 35, 36, 38 and 39. The prime numbers between 30 and 40 are 31 and 37. Note: 30 and 40 are also composite numbers.

Is the product of two prime numbers is always composite?

Yes, it is always. Assume temporarily that the product of two prime numbers is not always composite. This implies that that at least one product of prime numbers is also prime. Now, say two different prime numbers p and q, when multiplied, equal r. If r is a prime number, then r's only positive factors are 1 and r. But 1 is not a prime number. This contradicts that both p and q are prime (because either p or q MUST be 1). Therefore, the product of two prime numbers is always composite.

Are there any prime numbers that also square numbers give an example or explain why not.?

Square numbers can't be prime. They have too many factors.

What two composite numbers have 2 3 and 5 in their prime factorization?

30 is the composite number because 2x3=6x5=30 can also be divided by 3

Composite numbers vs prime numbers?

A composite number is a natural number that can be divided into smaller factors (which are also natural numbers). For example, 6 = 2 x 3. A prime number is an integer (greater than 1) that cannot be separated into smaller factors. For example, 7 can't be divided into smaller factors.
