The lowest common factor of any set of whole numbers would be 1. The way to find the least common factor would be to list all the factors of each number, determine which factors are common to all numbers, and then choose the smallest. However, that will be 1.
By remembering that the least common factor of any set of integers is 1.
All you have to do is memorize this: The least common factor of any set of nonzero positive integers is 1.

What is the greatest common factor of 400?
You need at least two numbers to find a GCF.
What is the greatest common factor of 245?
You need at least two numbers to find a GCF.
What is the greatest common factor of a factor tree?
You need at least two factor trees to find a GCF.
What is the greatest common factor for 12?
You need at least two numbers to find a GCF. There cannot be a greatest common factor if there are not at least two numbers to compare. The greatest common factor is the largest factor that all the numbers have in common - the largest factor that they all share.
What is the least common factor of 48 and 116?
The least common factor is the smallest factor that two or more numbers have in common. Thus, the least common factor of two numbers is 1. The least common factor of 48 and 116 is 1.
