Question

what are composite numbers? how do we find them ? difference between prime and composite number​

Answer 1

Answer:

A prime number has only two factors: 1 and itself. A composite number has more than two factors. The number 1 is neither prime nor composite. The prime numbers between 2 and 31 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29 and 31 since each of these numbers has only two factors, itself and 1.

Answer 2

Answer:

Composite numbers are numbers which have factors others than 1 and the number itself. In simple words, they are the numbers which can be divisible by numbers other than 1 and the number itself. All even numbers except 2 are composite numbers. Ex- 4,6,9, etc.

The difference between prime number and composite number is that prime numbers are divisible only with 1 and the number itself, while composite numbers have various other factors.
