Oh, isn't that a lovely question! To find the highest common factor (HCF) of 9, 54, and 18, we first look at the factors of each number. The factors of 9 are 1, 3, and 9; the factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54; and the factors of 18 are 1, 2, 3, 6, 9, and 18. The largest number that appears in the factors of all three numbers is 9, so the HCF of 9, 54, and 18 is 9. Isn't that just a happy little number to find?
