The factors of 8 are 1, 2, 4, and 8.

The factors of 15 are 1, 3, 5, and 15.

The only common factor is 1. Therefore, the least (smallest) common factor is 1, as is the greatest (largest) common factor.

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.

15 and 32 are relatively prime, which means that they share no factors aside from 1.
