Least common factor for two or more numbers is always 1. This is so because 1 is the factor of every number and the smallest natural number thus least common factor.
So, for 48, 54 and 72 LCF is also 1.
48/54 = 8/9 (common factor = 6)
The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.The greatest common factor of 42, 48, and 54 is 6
The least common factor of any set of integers is 1.
The least common factor of any set of integers is 1.
The least common factor is a term often mistakenly given to either the greatest common factor (GCF) or the least common multiple (LCM). This term is not often used because it does not describe a useful relationship between numbers. Since 1 evenly divides all integers, 1 is technically the least common factor for any set of integers.The smallest non-one common factor of 54 and 81 is 3.
