PRIME NUMBERS AND COMPOSITE NUMBERS

               

PRIME NUMBER - A natural number, which is divisible by 1 and itself and always greater than 1 is called prime number.

example-2, 3, 5, 7, 11, 13......and so on.

here, 2 is only even prime number, we can say Except 2, every prime number is an odd natural number.

1) Smallest even prime number is 2.
2) Smallest odd prime number is 3.

Largest prime number we can not obtained because prime number are infinitely exist.

COMPOSITE NUMBER - A natural number, which is greater than 1 and not prime.In other words we can say natural number which is divisible by more than two number, is called composite number.

example - 4, 6, 8, 9, 10,.....etc.

composite number can be even or odd.

1)Smallest composite number is 4.

2)Largest composite number we can not obtained because composite number are infinitely exist.

note - 1 is neither prime nor composite.
