Yes.

No they cannot. the factors of prime numbers are 1 and itself. if its factor has a composite number, then the original number would be composite.

Composite numbers can be written that way.

As for example 98 as a product of its prime factors is: 2*7*7 = 98

the prime factorization

That's a prime factorization.

yes

Yes, by definition!

To identify whether a number is prime or composite, look at its factors. A prime number has exactly two factors: one and itself. A composite number has more factors and can be written as the product of prime numbers. For example: Factors of 17: 1 and 17 so 17 is prime. Factors of 102: 1, 2, 3, 6, 17, 34, 51 and 102 so 102 is composite. It can be expressed as the product of prime numbers by prime factoring: 2 x 3 x 17

the numbers are odd

the prime factorization of the number

the prime factorization

Yes. For example 6 can be written as 2 x 3.

Composite numbers can be written as product of prime factors.

A prime number is one that has only 2 factors, itself and one. A composite number is one that can be written as the product of two numbers that are not itself. By these definitions, 1 and 0 fail to be either composite or prime. 1 can only be divided by one, so it does not have the 2 necessary factors to be prime or the multiple required to be composite. 0 on the other hand can be divided evenly by every number, but no two numbers that are not 0 can be multiplied to get a product of 0.

Composite numbers are the non prime numbers and have more than 2 factors. Some examples of composite numbers are 6, 8, 55 etc.

A composite number is an integer having more than two factors that are whole numbers.(Factors are two numbers that multiply together to give the number.) Some examples may help to get things in focus.2 has only two factors (1, 2) so it is not a composite number, it is a prime number.3 has only two factors (1, 3) so it is not a composite number, it is a prime number.4 has three factors (1,2,4) so it is a composite number.5 has only two factors (1,5) so it is not a composite number, it is a prime number.6 has four factors (1,2,3,6) so it is a composite number.Another description:A composite number is an integer that is exactly divisible by at least one factor other than 1 and itself. There is an infinite number of composite numbers. It is not a prime number.A prime number on the other hand has two distinct factors and can only be divided by 1 and itself.It's easy enough to infer that a composite number can be written as a product of prime factors:Example 2380 = 2 x 2 x 5 x 7 x 17The Fundamental Theorem of Arithmetic states that any integer greater than 1 can be written as a unique product of prime numbers. This is a very important theory in math!The first few composite numbers are: 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20.A number that is divisible.Example: 145 is a composite number because you can divide it by 5 and other numbers.

1 times number or number times 1

A composite number is an integer that is exactly divisible by at least one factor other than 1 and itself. There is an infinite number of composite numbers.A prime number on the other hand can only be divided by 1 and itself. It's easy enough to infer that a composite number can be written as a product of prime factors:Example2380 = 2 x 2 x 5 x 7 x 17The first few composite numbers are:4,6,8,9,10,12,14,15,16,18,20.Numbers which can be divided by other numbers besides 1. Numbers with factors besides 1 and themselves. Numbers which are not prime. 91 is composite because it is 13 x 7. But 41 is not composite because it is only 41 x 1.(of an integer) being the product of two or more factors greater than one; not prime.

Actually, 1 is composite. As for 0: "Zero has an infinite number of divisors (any nonzero whole number divides zero). It cannot be written as a product of two factors, neither of which is itself, so zero is also not composite. It falls in a class of numbers called zero-divisors. These are numbers such that, when multiplied by some nonzero number, the product is zero. " -Dr. Rob, the math forum

30 cannot be written as the product of 6 prime numbers. 30 has three prime factors: 2 x 3 x 5 = 30

15 is composite, because it can be written as the product of numbers besides itself and 1 (3 * 5 = 15). 17 is prime, because the only numbers that multiply to 17 are 1 and itself.

Every composite number ... that is, one that is not a prime ... can be written as the product of two or more prime numbers. The primes themselves are the exceptions. A prime number is the product of only ' 1 ' and itself, and ' 1 ' is not considered a prime number.

A composite number has more than two factors. A prime number has exactly two factors. A prime factor is a factor that is a prime number. All numbers can be written as a prime number or the product of prime factors. So, all composite numbers have prime factors. Here are examples: 10 = 2 x 5 11 = 11 12 = 2 x 2 x 3 13 = 13 14 = 2 x 7 15 = 3 x 5 16 = 2 x 2 x 2 x 2 Any number has itself as a factor, so all composite numbers have at least one composite factor - themselves. Some composite numbers have other composite numbers as factors, as well. If the composite number has only two (not necessarily distinct) prime factors, it will not have any other composite numbers as factors other than itself. Here are examples: 20 has factors 1, 2, 4, 5, 10, and 20, of which 4, 10, and 20 are composite numbers. 21 has factors 1, 3, 7, and 21, of which only 21 is a composite number. 22 had factors 1, 2, 11, and 22, of which only 22 is a composite number. 24 has factors 1, 2, 3, 4, 6, 8, 12, and 24, of which 4, 6, 8, 12, and 24 are composite numbers. A factor string of a composite number can be a combination of prime and composite factors that multiplied together equal the number. The prime factorization is a factor string with only the prime numbers. Here are examples: 24 has a factor string of 4 x 6, both of which are composite numbers, or 3 x 8, of which one is a composite number and one is a prime number, or 2 x 3 x 4, of which one is a composite number and two are prime numbers, or 2 x 2 x 2 x 3, which is the prime factorization. 20 has a factor string of 4 x 5, of which one is a composite number and one is a prime number, or 2 x 2 x 5, which is the prime factorization.

Yes. Do a factor tree to find the prime factors. Then write down all of those times together equals your original number.e.g. 12=6*2=2*2*3=which is written as two squared*3
