# Find GCD and LCM Using C Program

**GCD:** The *greatest common divisor* (GCD), which is also known as the *greatest common factor* (GCF), of two or more integers, is the largest integer that is a common divisor (factor) of all the given integers.

**LCM: **The *least common multiple* (LCM), which is also known as the *least common denominator* (LCD) in fractions, of two or more integers is the smallest integer that is a common multiple (denominator) of all the given integers. Continue reading
