is 45 prime or composite why?

A composite number is a number that can be divided evenly by more numbers than 1 and itself. It is the opposite of a prime number. The number 45 can be evenly divided by 1, 3, 5, 9, 15 and 45, with no remainder. Since 45 cannot be divided by just 1 and 45, it is a composite number.

Therefore all numbers that end with five and are greater than five are composite numbers. The prime numbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.

Composite number. ... So a composite number is one which is not a prime number or 1. Sometimes, the term composite number is used in a wider sense to include negative integers; a negative integer is composite if it is the negative of a (positive) composite number. Zero is neither prime nor composite.

A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers.

Composite Number. which is not prime (i.e., which has factors other than 1 and itself). The first few composite numbers (sometimes called "composites" for short) are 4, 6, 8, 9, 10, 12, 14, 15, 16, ... ... Note that the number 1 is a special case which is considered to be neither composite nor prime.

Composite numbers have more than two factors, and every composite number can be written as a unique product of primes. This is called the prime factorization of a number. When we write the prime factorization of a number, we are rewriting the number as a product of primes.

(... NO, forty-five (45) is NOT (emphasis, mine throughout) a prime number because it does not satisfy the definition of a prime number! By definition, a prime number is any positive integer that is exactly divisible by exactly two positive integers --- itself and 1.

A composite number has to have more factors then itself (2) and one (1). The only factors of two are one and two. This means two is a prime number and is not composite.

In order to be composite, you have to have more than two factors. You have to have 1, yourself, and some other things. So it's not composite. So 1 is neither prime nor composite.

23 is therefore a prime number. If it had 3 or more factors it would be composite. 1 is the only number which has 1 factor - it is neither prime nor composite. The number 23 , has only two factors ( 1 and itself), meaning that it is a prime number - not composite.
