The Number 7 is a Prime number
Composite. Its prime factors are 2×2×7.
91 is neither a prime nor a squared number. It is a composite having the prime factors 7 x 13.
A prime number can only have adivisorof itself and 1.Both 3 and 7 divide 21, so it cannot be a prime number.I.e.: 21/3 = 7 and 21/7 = 3A composite number has at least 1 divisor, and we already determined that both 3 and 7 are divisors, so:21 is a composite number21 is a composite number.
343 is composite -- it has factors 1, 7, 49 and 343. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime nor composite.

7 is a prime number but 1 is neither prime nor composite.
3 * 7 = 21 21 is not prime
511 = 73 x 7 therefore, it is a Composite number!

'98' is a COMPOUND Number. Compound numbers are the product of the multiplication of two( or more) smaller numbers. 2 x 49 = 98 ( So '98' is a compound number) NB Any even number , except '2' , is a compound number. Even numbers are those that end in 0,2,4,6,8 NNB Prime numbers always, except '2' itself, end in an odd number, except '5'. So e.g. 1,000,002 is Compound, it ends in '2' . It is NOT prime. 1,000,000,015 is a compound number, because it ends in '5'. The odd number exception.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 227 is prime.
