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 50 and 100 is 2.
The least common factor is: 1
The least common factor of any set of integers is 1.
There cannot be a least common factor of just one number. To be common there need to be at least two numbers.
The factors of 75 are: 1, 3, 5, 15, 25, 75 The factors of 100 are: 1, 2, 4, 5, 10, 20, 25, 50, 100 The common factors are: 1, 5, 25 The Greatest Common Factor: GCF = 25
1, 3 is next.* * * * *That is the least common factor (which is a meaningless concept), not the least common multiple!LCM(15, 45, 75) = 225
