What is the HCF of 4 and 8?

HCF of 4 and 8 by Prime Factorization As visible, 4 and 8 have common prime factors. Hence, the HCF of 4 and 8 is 2 × 2 = 4.

What is the HCF of 2/3 and 4?

1
The HCF of 2, 3, and 4 is 1. ∴ The highest number that divides 2, 3, and 4 is 1.

What is the HCF of 2 4 and 6?

HCF of 2, 4 and 6 by Prime Factorization As visible, 2, 4 and 6 have only one common prime factor i.e. 2. Hence, the HCF of 2, 4 and 6 is 2.

What is the HCF of 4 and 9?

Answer: HCF of 4 and 9 is 1.

What is the HCF of 5 and 10?

Prime factorization of 5 and 10 is (5) and (2 × 5) respectively. As visible, 5 and 10 have only one common prime factor i.e. 5. Hence, the HCF of 5 and 10 is 5.

Which is the least common multiple of two numbers?

LCM: Least Common Multiple of two numbers is the number that is a common multiple of the both the numbers. Below is a program to find LCM of two numbers using recursion.

How to find LCM of two numbers in C + +?

C++ Program to Find LCM. C++ Programming Server Side Programming. The Least Common Multiple (LCM) of two numbers is the smallest number that is a multiple of both. For example: Let’s say we have the following two numbers: 15 and 9. 15 = 5 * 3 9 = 3 * 3. So, the LCM of 15 and 9 is 45. A program to find the LCM of two numbers is given as follows −.

Which is the smallest LCM of two numbers?

LCM (Least Common Multiple) of two numbers is the smallest number which can be divided by both numbers. For example LCM of 15 and 20 is 60 and LCM of 5 and 7 is 35.

How to find the LCM in a program?

In the above program, the LCM is found using the formula. First, the GCD of a and b is obtained using gcd (). Itis a recursive function. It has two parameters i.e. a and b. If b is greater than 0, then a is returned to the main () function. Otherwise the gcd () function recursively calls itself with the values b and a%b.
