What do you do with HCF?

HCF by Listing out the Common Factors

In this method, we list out the factors of each number and determine the common factors of those numbers. Then, among the common factors, we determine the highest common factor. Let's understand this method using an example. We will find the HCF of 30 and 42.

When would you use HCF and LCM in real life?

1) To split things into smaller sections. 2) To equally distribute 2 or more sets of items into their largest grouping. 3) To figure out how many people we can invite for a party. 4) To arrange something into rows or groups.
