The highest common factor (HCF) of 30, 40, and 50 is 10. To find the HCF, you can factorize each number into its prime factors: 30 = 2 x 3 x 5, 40 = 2^3 x 5, and 50 = 2 x 5^2. Then, identify the common prime factors among the numbers and multiply them to find the HCF, which in this case is 2 x 5 = 10.
