C Program to Check Whether a Number is Prime or not
WebOct 1, 2024 · Here, we use the concept of HCF. Two numbers are co-prime if their HCF is equal to 1. We apply this concept to our algorithm. The algorithm starts off by taking the two numbers to be checked as user input. We store these values into two variables: say n1 and n2. We initialize the HCF of the two numbers as 1. WebApr 27, 2011 · Now condition 3. a < m < b i.e 2 < 3.46 < 6. So to check prime we only need to check for number less than 3.46 which is 2 to find out that number is not prime. Hence, check divisibility by numbers less than or equal to(if n = 4, m=a=b=2) square root of n. – WebSep 12, 2024 · Step 3: Declare and initialize the variable reverse and assign input to a temp variable tempNum=num. Step 4: Start the while loop until num !=0 becomes false. rem = num % 10. reverse*= 10 + rem. num = num / 10. Step 5 : Check if reverse == tempNum. Step 6: If it’s true then the number is a palindrome. Step 7: If not, the number is NOT a ... shangar connors
