If the number has a remainder of 2 or 4 when divided by 6, it is an even number, so it is not Prime number.
6n + 2 = 2 (3n + 1), so it is divisible by 2.
6n + 4 = 2 (3n + 2), so it is divisible by 2.
If the number has a remainder of 3 when divided by 6, it is divisible by 3, so it is not a prime number.
6n + 3 = 3 (2n + 1), so it is divisible by 3.
However, there are two prime numbers that do not have a remainder of 1 or 5 when divided by 6 : 2 and 3

The definition of a prime number is a number that can only be divided by 1 and itself. Prime numbers can not be divided by anything but 1.
The prime factorization of 85 is 5 x 17. Both 5 and 17 are prime numbers, and when multiplied together, they equal 85. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves without leaving a remainder.
The factors of 72 that are prime numbers are 2, 3, and 5. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves without leaving a remainder. In the case of 72, it can be broken down into the prime factors 2^3 * 3^2, where 2 and 3 are the prime factors.
prime number-a number that can only be divided by 1 or itself without resulting in a remainder therefore if the product (multiplying) of 2 prime numbers could be divided by either of the prime numbers, 1, and itself. example 2X3=6 6/1=6 6/6=1 6/3=2 6/2=3
A composite number is when it can be divided evenly by numbers other than 1 or itself. A prime number can be divided, without a remainder, only by itself and by 1. Therefore, zero is neither a composite, nor a primary number.
