Is 4 A Composite Number?

• Yes, number 4 is a composite number.
• Four is a composite number, because it has more divisors than 1 and itself.

Is 4 A Prime Number?

• No the number 4 is not a prime number.

What Are The Prime Factors Of Four?

• The prime factors of number 4 are: 2
• Equcation for number four factorization is: 2 * 2

How To Calculate Composite Numbers

• So, if n > 0 is an integer and there are integers 1 < a, b < n such that n = a * b, then n is composite. By definition, every integer greater than one is either a prime number or a composite number. The number one is a unit, it is neither prime nor composite. For example, the integer 14 is a composite number because it can be factored as 2 * 7. Likewise, the integers 2 and 3 are not composite numbers because each of them can only be divided by one and itself.
• Every composite number can be written as the product of two or more (not necessarily distinct) primes, for example, the composite number 299 can be written as 13 * 23, and that the composite number 360 can be written as 23 * 32 * 5; furthermore, this representation is unique up to the order of the factors. This is called the fundamental theorem of arithmetic.
