The factors of 4 are 1, 2, 4

The factors of 5 are 1, 5

The factors of 6 are 1, 2, 3, 6

The ONLY factor they share 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.
