Prime Number is a natural number greater than 1 that has exactly two distinct natural number divisors: 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example, 13 can only be divided by 1 and by 13 itself. Here is a list of all the prime numbers up to 100: 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47, 53,59,61,67,71,73,79,83,89,97,.. 1 is not a prime number as in definition “For a number to be prime it must have two d istinct (different) factors. Algorithm Step1: Input the number(n) to check for prime number Step2: If n is below or equal to 1 then go to step 12 Step3: if n is equal to 2 then go to step 11 Step4: Assign variable count =n / 2 Step5: Assign variable a=1 Step6: Add 1 to a and store it to variable a Step7: remainder = n % a Step8: if remainder=0 then go to step 12 Step9: subtract one from count and store it to variable count Step10: if count is not equal to 0 then go to s...
