To find the prime factors of a composite number, try dividing it by each of the prime numbers less than its square root.

For example, to find the prime factorization of 338 these primes are 2, 3, 5, 7, 11, 13, and 17, but 338 can only be divided by 2 and 13 without remainder.

338/2=169

169/13=26

26/13=2

Each of these divisors are prime factors of 338, and when arranged in ascending order, the prime factorization of 338 is 2 x 13 x 13 or 2 x 132.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

How do you figure out a composite number?

A number can be factored to determine whether it is prime or composite. A prime number has exactly 2 factors, 1 and the number itself. A composite number has more than two factors.


What are the prime factors of a composite prime number?

There is not such a thing as a composite prime number. A prime number has exactly two factors. A composite number has more than two factors.


What occurs when the composite number is expressed as a number of factors that are all prime?

When a composite number is expressed as a product of its prime factors, the prime factorization of the composite number has been performed.


How do you check if a number is prime or a composite number?

A number is prime when it only has one and itself as factors is prime. Therefore, to tell if a number is prime or composite simply find it's factors. If it has more than two factors than it is not a prime number, it is composite.


Is 713 a prime or composite number?
