The Highest Common Factor (HCF) of 36, 44, 52, and 56 can be found by determining the prime factors of each number. The prime factors of 36 are 2^2 * 3^2, of 44 are 2^2 * 11, of 52 are 2^2 * 13, and of 56 are 2^3 * 7. To find the HCF, we look for the highest power of each common prime factor among the numbers, which in this case is 2^2 = 4. Therefore, the HCF of 36, 44, 52, and 56 is 4.
