Prime factorization involves rewriting numbers as products
The HCF and the LCM of 1848, 132 and 462 are 66 and 1848 respectively
<h3>How to determine the HCF</h3>The numbers are given as: 1848, 132 and 462
Using prime factorization, the numbers can be rewritten as:
The HCF is the product of the highest factors
So, the HCF is:
In (a), we have:
So, the LCM is:
Hence, the HCF and the LCM of 1848, 132 and 462 are 66 and 1848 respectively
