Is there a link between GCF and LCM?

If you haven’t encountered it yet, there is a remarkable algebraic relationship or link between the Greatest Common Factor (GCF) and the Least Common Multiple (LCM) of two numbers. In this lesson, the numbers that we want are those belonging to the set of positive integers only.

How to find LCM and GCF in purplemath?

LCM and GCF. Purplemath. To find either the Least Common Multiple (LCM) or Greatest Common Factor (GCF) of two numbers, you always start out the same way: you find the prime factorizations of the two numbers.

How to find the least common multiple LCM?

How to Find the Least Common Multiple LCM 1 Listing Multiples 2 Prime Factorization 3 Cake/Ladder Method 4 Division Method 5 Using the Greatest Common Factor GCF

What does it mean when a number is the GCF?

Since 1 divides into everything, then the greatest common factor in this case is just 1. When 1 is the GCF, the numbers are said to be “relatively” prime; that is, they are prime, relative to each other.
