Week 7 Tasks

Task 31 (Experiment 13)

WAP to find the LCM and GCD of two given numbers using while loop.

Hint:
If a and b are the two numbers entered by the user then GCD of them is the largest number which is not greater than a and b and also is divisible by both a and b. Once GCD is known simply use the formula to find LCM $$ LCM = \frac{a * b}{GCD} $$

Task 32 (Experiment 14)

Write a C program to find if the entered three digit number is an Armstrong number or not using do while loop.

When the sum of the cube of the individual digits of a three digit number is equal to that number, the number is called Armstrong number. For example 153.

$$ 1^3 + 5^3 + 3^3 = 153 $$

Task 33

Write a program in C to convert a decimal number into binary using while loop.

Hint

Task 34

WAP to convert binary number to decimal number using while loop.

Task 35

Write a C program to find Strong Numbers within a range of numbers using do while loop.

Hint

If sum of factorial of digits is equal to original number then it is Strong number
