The least common factor of two numbers is the smallest positive integer that both numbers can be evenly divided by. To find the least common factor of 121 and 144, we first need to determine the factors of each number. The factors of 121 are 1, 11, and 121, while the factors of 144 are 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144. The least common factor of 121 and 144 is 1, as it is the smallest positive integer that both numbers can be divided by without any remainder.

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.

121 and 144 are relatively prime, which means that they share no factors aside from 1.
