The highest common factor (HCF) of 30, 60, and 120 is 30. To find the HCF, you can list the factors of each number and then identify the largest factor that is common to all three numbers. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120. The highest common factor among these three sets of factors is 30.
