1 is not a Prime number. It is neither prime nor composite. It is known as unity. A prime number is a number with exactly two factors: 1 and itself. Since 1 has only one factor, it is not a prime number.

The first prime number is 2. The second is 3. The third is 5. The fourth is 7. The fifth is 11. etc. However numbers can be "mutually prime" even when the numbers themselves are not prime numbers.
