The Highest Common Factor (HCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF of 168 and 252, we first list the factors of each number: 168 (1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168) and 252 (1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252). The common factors are 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, and 84. Therefore, the HCF of 168 and 252 is 84.
