Their product.
The LCF, or least common factor,of any two or more numbers will always be 1.
The LCF is 1. The GCF is 4.
The least common factor, for any two integers, will always be 1. Finding the LCF is, therefore, a pointless exercise.
The least common factor of any two integers is ' 1'.In the case of 5 and 9, it's also their greatest common factor.
