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.

What is the greatest common factor of 72 144 and 216?

To find the greatest common factor (GCF) of 72, 144, and 216, we first need to factorize each number. The prime factorization of 72 is 2^3 * 3^2, 144 is 2^4 * 3^2, and 216 is 2^3 * 3^3. The GCF is found by identifying the common prime factors with the lowest exponents, which in this case are 2^3 * 3^2, resulting in a GCF of 72.
