The highest common factor (HCF), also known as the greatest common divisor (GCD), is the largest number that evenly divides two given numbers. To find the HCF between 27 and 102, first list the factors of each number. The factors of 27 are 1, 3, 9, and 27, while the factors of 102 are 1, 2, 3, 6, 17, 34, 51, and 102. Comparing the two sets of factors, the largest number that appears in both lists is 3. Therefore, the highest common factor between 27 and 102 is 3.
