For example, the HCF of 2 and 4 is 2, because 2 is the number which is common to both 2 and 4. while loop checks the condition 35>0 is true , temp=35, n2=5, n1=35, 5>o true,temp=5,n2=0,n1=5. C HCF of two numbers output. 2) Using scanner object, read the values and store in the variables n1, n2. If the program has two variables a and b where a = 4 and b = 5, after swapping them, a = 5, b = 4. In the function, we first determine the smaller of the two numbers since the H.C.F can only be less than or equal to the smallest number. Let us solve an example when we need to find the HCF of three numbers. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page. Solution: By prime factorisation, we can write the two numbers; 24 = 2 x 2 x 2 x 3. Solution: By prime factorisation, we can write the given numbers as; Taking out the common factors of 126, 162 an d180, we get: Put your understanding of this concept to test by answering a few MCQs. 3)The while loop iterates until n2>0 is false temp assigned to n2, n2 assigned to the remainder of n1/n2, n1 assigned to n1.
