# C Program to Find the GCD and LCM of Two Integers1 min read

The post on C program calculates the GCD and LCM of two integer numbers.

GCD(Greatest Common Divisor) or HCF: Largest Integer that can divide both the numbers without any remainder or with 0 as remainder. For example, the GCD or HCF of 36 and 48 is 12.

LCM(Least Common Multiple): The LCM of two integers is the smallest positive integer that is perfectly divisible by both the numbers (without a remainder). For example, the LCM of 16 and 24 is 48.

## C Program to find HCF and LCM of two Integer Number

Output:

`Enter 2 Numbers: 36 48 GCD is: 12 LCM is: 144`

## C Program to find HCF and LCM using Recursion

Output:

`Enter 2 number: 36 48 GCD of 36 and 48: 12 LCM of 36 and 48: 144`
