How can we learn prime numbers and composite numbers between 1&100 easily?
A prime number is a positive integer that is only divisible by two factors: 1 and itself. In contrast, a composite number is a number that is divisible by numbers other than 1 and itself - in other words, not a prime number.
All even numbers are composite numbers .
If we know the rules of division by 3 , 5, 6,7,8,9 we can find it easily.
The prime numbers between 2 and 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89 and 97.
