Greatest common divisor base case

WebThe greatest common divisor (GCD), also called the greatest common factor, of two numbers is the largest number that divides them both.For instance, the greatest common factor of 20 and 15 is 5, since 5 divides both 20 and 15 and no larger number has this property.

Greatest Common Divisor: Meaning, Examples & Rules

WebThe Greatest Common Factor, the GCF, is the biggest (that is, the "greatest") number that will divide into (that is, the largest number that is a factor of) both 2940 and 3150. In other words, it's the number that contains all the factors *common* to both numbers. In this case, the GCF is the product of all the factors that 2940 and 3150 share.
