The Highest Common Factor (HCF) of 165, 195, and 285 is the largest number that divides all three numbers evenly. To find the HCF, we first factorize each number: 165 = 3 x 5 x 11, 195 = 3 x 5 x 13, and 285 = 3 x 5 x 19. Then, we identify the common factors among the three numbers, which are 3 and 5. Therefore, the HCF of 165, 195, and 285 is 15 (3 x 5).
The factors of 165 are 1, 3, 5, 11, 15, 33, 55, and 165. The factors of 182 are 1, 2, 7, 13, 14, 26, 91, and 182. The highest common factor of 165 and 182 is 1.
It is: 44
