First of all let us understand what are prime numbers.
What are prime numbers?
=> A prime number is a number which occurs in the table of 1 and the number itself. It cannot be divided by another number or occurs in another table. Prime numbers from 1 to 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, 87, 97 respectively.
Now let us understand what are composite numbers.
What are composite numbers?
=> The number divisible by other numbers too including 1 and the number itself are called composite numbers. Composite numbers from 1 to 100 are 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 81, 82, 84, 85, 86, 88, 90, 91, 92, 93,94, 95, 96, 98, 99, 100 respectively. They are the numbers except prime numbers.
