Why is 1 prime or composite?

As 1 has only one positive divisor (1 itself), it does not meet the criteria to be a prime. Similarly, a composite number is a number that can be rewritten as the product of two integers both larger than 1, and 1 does not meet that criteria too. Hence 1 is neither prime nor composite. via

How do you know if a number is composite?

  • If a number less than 121 isn't divisible by 2, 3, 5, or 7, it's prime; otherwise, it's composite.

    What are the first 3 odd composite numbers?

    All the odd numbers which are not prime are odd composite numbers. For example, 9, 15, 21, 25, 27 are odd composite numbers. Consider the numbers 1, 2, 3, 4, 9, 10, 11, 12 and 15. Here 9 and 15 are the odd composites because these two numbers have odd divisors and satisfy the composite condition. via

    Is 7 and 15 coprime numbers?
