The Highest Common Factor (HCF) of 18, 36, and 72 is 18. To find the HCF, you can factorize each number into its prime factors: 18 = 2 x 3^2, 36 = 2^2 x 3^2, and 72 = 2^3 x 3^2. The HCF is the product of the common prime factors raised to the lowest power they appear in any of the numbers, which in this case is 2 x 3^2 = 18.
