SUMMARY
The Highest Common Factor (HCF) of the numbers 4, 6, 8, and 18 is definitively 2, as determined by analyzing their prime factors and the differences between the numbers. The Lowest Common Multiple (LCM) of these numbers is 72, derived from the multiples of each number. The discussion emphasizes that since 8 is a multiple of 4 and 18 is a multiple of 6, one can simplify the LCM calculation by focusing on the LCM of 8 and 18. This approach streamlines the process of finding the LCM.
