For Highest Common Factor(HCF), express the number as a product of its prime numbers. The HCF is the product of the prime numbers raised to the power of the lower of their respective indices of the two.

For Lowest Common Multiple (LCM), express the number as a product of its prime numbers. The LCM is the product of the prime numbers raised to the power of the higher of their respective indices of the two.
