What is the difference between lcm and gcd

For example, when creating a list of the multiples of 6 and As we can see, the lowest integer shared by both 6 and 9 is 18 —it is divisible by 1, 6, 9, and itself. The biggest difference between the GCF and the LCM is that one is based upon what can divide evenly into two numbers GCF , while the other depends on what number shared between two integers can be divided by the two integers LCM.

One must also consider if the numbers only share itself and 1 as common multiples of factors, than those numbers are not related to each other. Summary: 1. The GCF is based upon what integer divides evenly into two numbers; the LCM is based upon what integer two numbers share in a list of multiples. Cite APA 7 ,.

MLA 8 ,. This article has a small error. For example the GCF of 64 and 56 is 8 and 8 is a composite number! Please fix the error. And the exact LCM of 15 and 18 is M and H. F is equal to the product of these two numbers.

And to calculate the HCF by the prime factorization method take two random numbers and To calculate HCF by division method, simply follow the mentioned below steps:. For example, suppose two different numbers 12 and The greatest common factor of these numbers is:.

Several useful online calculators are available to find the greatest common factor. Most of the tools provide the following methods to check the highest common factor and least common multiple:.

The lowest common multiple LCM is the lowest number that is a multiple of two numbers. For example, multiples of 2 are 2, 4, 6, 8 etc, and multiples of 3 are 3, 6, 9, 12 etc, so the LCM of 2 and 3 is 6.

This is most commonly used when adding, subtracting etc fractions with different denominators.
