Question

Why all prime numbers except 2 are odd numbers ?​

Answer 1

Answer:

because even numbers have both even and odd factor except 2 , while odd numbers have only odd factors.

Answer 2

Step-by-step explanation:

NOTE: A Prime Number is a number that has only 2 factors:

1.) Number itself and

2.) One (1)

Every even number (except 2) would have a minimum of 3 factors:

1.) Number itself

2.) One (1) and

3.) Two (2)

making them composite numbers.

Whereas, Two (2) has only 2 factors : 1 & 2.

Thus, all prime numbers are odd (except 2).
