All sets of numbers have an LCF of 1, so I'll assume you meant to write least common multiple.
6 and 72 have a GCF of 6 and an LCM of 72. So do 18 and 24.
The largest of the common factors of numbers is known as the greatest common divisor or greatest common denominator. The smallest common factor is called the lowest common divisor.
When the lowest number is a factor of the other two.
The least (meaning lowest) common factor of any set of whole numbers is always 1. The greatest common factor of any set of whole numbers will depend on the factors of the individual whole numbers in the set.
An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.An expression is in its lowest terms if the greatest common factor of the numerator and denominator is one.
1 is the greatest common factor of any fraction in lowest terms.
The lowest common factor of any set of numbers is 1.
The lowest common factor of any set of numbers is 1.
The lowest common factor of any set of numbers is 1.
There is no answer. There cannot be a lowest common multiple of a single number, such as 30, because "common multiple" means a multiple that two or more numbers have in common. Likewise, there cannot be a highest common factor of a single number, such as 3, because "common factor" means a factor that two or more numbers have in common.
The least common factor of any set of numbers is 1.
The lowest common factor of any set of numbers is 1.
The lowest common factor of any set of numbers is 1.
