The least common factor is: 1
The least common factor of any set of numbers is 1.
The least common factor is 1. (The least common factor of any two or more positive integers is always 1.)
The least common factor is 1. (The least common factor of any two or more positive integers is always 1.)
What is the greatest common factor shared by 40 and 20?
The GCF of 8 and 20 is 4, and the LCM of 8 and 20 is 40.
The least common factor is: 1
The least common factor is: 1
The highest common factor is: 20
There can be only one greatest common factor for any set of numbers. GCF(40, 20) = 20.
The least common factor of any set of integers is 1.
Since 20 is a factor of 40, it is automatically the GCF.
